Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, completeGround is described, and obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment. BaseEmbodiment in the present invention, those of ordinary skill in the art are not making obtain under creative work prerequisite allOther embodiment, belong to the scope of protection of the invention.
The present invention relates to a kind of miniature gears rotary switch device, it comprises: direct current generator 1, driving wheel 2, driven pulley 3, twoIndividual thrust spring 4. In conjunction with Fig. 1, two thrust springs 4 are arranged symmetrically in driven pulley 3 both sides. Wherein, direct current generator 1Coaxial with driving wheel 2, direct current generator 1 drives driving wheel 2 can do forward (also clockwise) and rotates or reverse (counterclockwise)Rotate. In a specific embodiment, thrust spring 4 can be rubber elastomer, and preferably, thrust spring 4 is selected sheetOr column spring. In another specific embodiment, thrust spring 4 can be metal spring.
Fig. 2 is according to the structural representation of each funtion part of driven pulley of apparatus of the present invention, in conjunction with Fig. 2, and driven pulley3 are designed to each functional parts such as the gap that has local gear, spacing preiection and realize smart lock folding. Particularly, as figureShown in 2, the part that only accounts for whole circumference 1/6 to 1/3 on driven pulley 3 is distributed with gear, that is to say, on driven pulley 3Only have the cambered surface of 60 ° to 120 ° to be distributed with gear. Preferably, on driven pulley 3, only account for the part distribution of whole circumference 1/4There is gear, that is to say, on driven pulley 3, only have in 90 ° of cambered surfaces and be distributed with gear. On the circumference of driven pulley 3, having one slitsMouthfuls 31, when gap the 31 corresponding lateral attitude apparatus of the present invention in opening, apparatus of the present invention when gap leaves lateral attitudeIn closure state. Continue referring to as Fig. 2, respectively there is a spacing preiection 32 driven pulley 3 two sides, this spacing preiection 32 along withThe rotation of this rotary switch device, can touch thrust spring 4.
Fig. 3 show that driving wheel 2 of the present invention turns clockwise (being also rotated in the forward) thus drive driven pulley 3 to rotate untilThe structural representation that the gear of driven pulley 3 departs from from driving wheel 2. Shown in Figure 3, direct current generator 1 drives driving wheel 2Rotate, now driving wheel 2 drives driven pulley 3 to rotate thereupon. There is gear because driven pulley 3 only has local distribution, work as driven pulley3 rotate after one section of cambered surface under the drive of driving wheel 2, and driven pulley 3 can be thrown off with the annular tooth of driving wheel 2. Again due to drivenTake turns 3 two sides and be respectively designed with a spacing preiection 32, after driven pulley 3 and the annular tooth of driving wheel 2 are thrown off, on driven pulley 3The spacing preiection 32 of one side can arrive thrust spring 4 in top. Now spacing preiection 32 makes thrust spring 4 to the pushing of thrust spring 4It is produced to deboost, thus make the tooth of driven pulley 3 can be oppositely near driving wheel 2 and unlikely two gears engagements depart from. FigureArc dotted line on driven pulley 3 shown in 3 has showed the rotation direction that driven pulley 3 is promoted by driving wheel 2. Thrust spring 4On dotted arrow show that thrust spring 4 is subject to the pressure of the spacing preiection 32 on driven pulley 3 and the reaction force that produces, fromIn Fig. 3, can find out, this reaction force can make the tooth unlikely and driving wheel 2 of the tooth on driven pulley 3 throw off.
And in the time that driving wheel 2 enters reverse rotation, can drive driven pulley 3 to make counteragent. It is contrary that Fig. 4 shows driving wheel 2Thereby drive driven pulley 3 rotates, the gear of driven pulley 3 is de-from driving wheel 2 in hour hands rotation (also i.e. reverse rotation)From structural representation. As shown in Figure 4, in the time that control direct current generator 1 counter-rotates driving wheel 2, due to driving wheel 2Still in engagement, driving wheel 2 still can drive driven pulley 3 to counter-rotate with the tooth of driven pulley 3.
Course of action below in conjunction with Fig. 5 and Fig. 6 miniature gears rotary switch device of the present invention in opening.
Fig. 5 shows on driven pulley 3 state when gap 31 approaches lockset position of coupler, in conjunction with opening of Fig. 5 apparatus of the present inventionLock course of action. In the time that needs are opened miniature gears rotary switch device, drive direct current generator 1 to drive driving wheel 2 forwards to revolveTurn, driven pulley 3 is done counter-rotating under the drive of driving wheel 2, and the gap on driven pulley 3 also rotates thereupon and approach unlock positionPut. As shown in Figure 5.
Fig. 6 shows the state while approaching lockset position of coupler according to the gap 31 on the driven pulley 3 of apparatus of the present invention. With reference to 6, figureShow, driven pulley 3 arrives behind enable possition, the part engagement that is out of gear, 3 of driven pulleys stop the rotation, now this device inOpening. Now spacing preiection 32 tops on driven pulley 3 are to thrust spring 4, and thrust spring 4 produces spacing preiection 32Opposition, thus make the tooth of driven pulley 3 can be oppositely near driving wheel 2 and the engagement of unlikely gear departs from, thereby be this dressPutting two gears rotates backward ready.
Course of action below in conjunction with Fig. 7 apparatus of the present invention when the closure state.
Fig. 7 shows the position view of driving wheel 2 reverse rotation when approaching closure state. As shown in Figure 7, work as the present inventionMiniature gears rotary switch device need when closed, to drive direct current generator 1 to drive driving wheel 2 to counter-rotate, driven pulley 3 is withAction counter-rotating, on it, gap 31 is also rotated away from enable possition thereupon and enters closure state.
Otherwise, when driven pulley 3 arrives after closing position, the part engagement that is out of gear, driven pulley 3 stops the rotation, now thisBright device is in closure state. In like manner, because opposite side spacing preiection 32 tops on driven pulley 3 are now to the thrust spring of this side4, this spacing preiection 32 is subject to the opposition with the thrust spring 4 of its homonymy, makes the tooth of driven pulley 3 can be oppositely closeThe driving wheel 2 and engagement of unlikely gear is departed from, thus be that apparatus of the present invention two gear counteragents are ready.
In a preferred embodiment, two teeth that driven pulley 3 cogs on limit are designed to heteromorphic teeth. Fig. 8 shows drivenThe polymorphic structure schematic diagram of wheel two heteromorphic teeths up and down on both sides Shang Xia 3, Fig. 9 is the part of upper and lower two heteromorphic teeths of driven pulley 3Enlarged drawing. As indicated in two arrows on Fig. 8, two teeth on the limit of driven pulley 3 gears are designed to the abnormity of nonstandard involuteTooth. Shown in Fig. 9, the gear compound graduation circle of these two heteromorphic teeths is the standard involute of 20 ° of pressure angles to tooth root, reference circleBe chosen as the nonstandard involute of 22.5 ° of pressure angles to outside circle. Such heteromorphic teeth structural design make gear compound graduation circle withBe standard tooth form down, and the facewidth of part is larger more than reference circle. In the time that driving wheel 2 oppositely engages with driven pulley 3, initiativelyWheel 2 more easily engages with driven pulley 3, even have form and position tolerance between two gears, also can not cause rotating backward to enter nibblingWhile closing, it is stuck that two crowns form, thereby ensured between two gears and can reliably oppositely engage.
Continue in conjunction with Fig. 8 and Fig. 9, because on driven pulley 3, first is reversed meshed gears reference circle and remains belowStandard involute, when driving wheel 2 engages rotation with driven pulley 3, two teeth rotate progressive be engaged to reference circle following after, two gearsBetween cog relative movement orbit just engages according to the profile of tooth of master gear again, thereby makes follow-up gear be able to positive engagement and transmission.
Be more than the description of this invention, design under the prerequisite of spirit the common engineering in this area not departing from the present inventionVarious distortion and replacement that personnel make technical scheme of the present invention, all should fall into the definite guarantor of claim of the present inventionProtect in scope.
