Detailed description of the invention
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
nullAs Figure 1-4，A kind of automobile rearview mirror 10 rotary positioning apparatus，Automobile rearview mirror 10 is rotatably attached on automobile by connector 11，Rotary positioning apparatus includes: the motor 1 being arranged in rearview mirror 10、The connection seat 2 that be connected fixing with motor 1 and be connected the centring ring 3 that seat 2 form fit is fastened togather，Centring ring 3 and connection seat 2 coaxial connection connector 11，Connect seat 2 through hole is embedded with the first snap ring 4，One end face cincture of the first snap ring 4 be provided with one week jog 4341，The seat 2 that connects of the first snap ring 4 outer circumferential is provided with the limited block 5 of annular array，The second snap ring 6 and the first snap ring 4 shape that centring ring is provided with are coincide，Stopper slot 7 it is additionally provided with on centring ring 3，What limited block 5 can rotate along centring ring 3 axle center is arranged in stopper slot 7，Motor 1 drives the first snap ring 4 to rotate.
Jog 4341 is that three equal-sized recesses 42 and three alternate annulars arranging formation of equal-sized protuberance 43, protuberance 43 and recess 42 adjacent are with the buffering suface 8 tilted.Second snap ring 6 end face is provided with the structure coincideing with protuberance 43 and recess 42 shape, first snap ring 4 and the second snap ring 6 by jog 4341 structure be designed to be fastened togather closely, when the first snap ring 4 or the second snap ring 6 rotate around axle center, another snap ring corresponding can be with rotating with it, when three recesses 42 and three spaced structures of protuberance 43 enable to rotate, what torsional forces can more balance transmits between the first snap ring 4 and the second snap ring 6.
Limited block 5 is less than the stopper slot 7 width in the second outer circumference of snap ring 6 at the width of the first outer circumference of snap ring 4, limited block 5 can be along 7 liang of end motions of stopper slot, the width of stopper slot 7 deducts the width of limited block 5 and is the width that limited block 5 can rotate in stopper slot 7, and the radian that this width is corresponding that is to say the radian that rearview mirror 10 can rotate relative to connector 11.First snap ring 4 periphery and the second snap ring 6 periphery the most uniform be provided with three limited blocks 5 and three stopper slots 7, stopper slot 7 two ends are equipped with buffering suface 8, and limited block 5 two ends are also equipped with buffering suface 8.Be close to inside limited block 5 first snap ring 4 periphery, three stopper slots 7 and three corresponding limited blocks 5 be designed to ensure in the case of motor 1 drives rearview mirror 10 to rotate: connecting and rotating against more steady between seat 2 and centring ring 3, stress more balances；In the case of manual actuation rearview mirror 10 rotates, limited block 5 and protuberance 43 climb shifting lifting along buffering suface 8 simultaneously, and buffering suface 8 ensure that, when limited block 5 edge and protuberance 43 climb shifting lifting lifting, process is the most stable, is conducive to the most firmly.
The buffering suface 8 of limited block 5 one end is concordant with the buffering suface 8 of protuberance 43 one end, concordant buffering suface 8 make the first snap ring 4 and limited block 5 when rotating to two end positions, stress simultaneously, and stress is easier to share each other.
Connect and be additionally provided with axis ring 12 inside the first snap ring 4 on seat 2, axis ring 12 is provided with draw-in groove 13, axis ring 12 connects connector 11 by rotating shaft is fixing, axis ring 12 can be stablized and coaxially makes rotating shaft go here and there to be enclosed within connection seat 2, centring ring 3 and connector 11 simultaneously, draw-in groove 13 can be more firm with rotating shaft circumference key or groove buckle, connect relatively stable.
Connect the through hole of seat 2 and being fixed together that spacing collar is coaxially close to, first snap ring 4 and the second snap ring 6 are mutually closely fastened togather, limited block 5 is arranged in stopper slot 7, in motor 1 is fixedly installed on rearview mirror 10 simultaneously, motor 1 one end is fixing connects seat 2, drive end drive connection first snap ring 4 of motor 1.(1) present invention is when motor 1 drives rearview mirror 10 rotary work, motor 1 is when driving the first snap ring 4 to rotate, first snap ring 4 drives the second snap ring 6 to rotate, due to the mutual restriction between limited block 5 and stopper slot 7, rearview mirror 10 is merely able to turn an angle relative relative to connector 11, and two corresponding end values of the angle rotated also are buffered face 8 defined；(2) present invention is when manual actuation rearview mirror 10 rotary work, limited block 5 and protuberance 43 rotation that exerts a force are climb shifting along buffering suface simultaneously, make limited block 5 depart from the restriction of stopper slot 7, and make protuberance 43 depart from centring ring 3 to limit, it is possible to normal rotation skips the circulation of one or more hole clipping.
Desirable embodiment according to the present invention is enlightenment above, and by above-mentioned description, related personnel can carry out various change and amendment completely in the range of without departing from this invention technological thought.The content that the technical scope of this invention is not limited in description, it is necessary to determine technical scope according to right.
