Description

Drive mechanism for toy

The utility model relates to a kind of walking mechanism, especially relates to a kind of walking mechanism of toy.

Though the toy human or animal mode of appearance of Xiao Shouing is different in the market, move ever-changingly, the time all lack sense true to nature in walking, this mainly shows on two pin of toy, thereby makes the toy can not be to superior development.

The purpose of this utility model is to provide a kind of imitation walking mechanism true to nature of toy.

In order to realize above-mentioned purpose of the present utility model, the utility model provides a kind of walking mechanism of toy, it comprises that one has the bearing of two sidewalls, transmission device and two pin that a drive unit, has a pair of output gear, and described drive unit and transmission device are arranged on the described bearing; It also comprises a pair of hyperbolic axle and pair of links parts; Described hyperbolic axle is arranged on the described sidewall respectively rotationally and its bent axle is partly stretched in the described sidewall outside, and two bent axles of each described hyperbolic axle partly lay respectively on the both sides of its axis and the d-axis part that described output gear is fixedly installed on described hyperbolic axle; Each described linkage component comprises a guide rod, a pilot pin, a rocking bar and first, second connecting rod; The top of described guide rod offers a straight trough and its middle part and lower end and is hinged on an end of described a pair of bent axle and the preceding upper lateral part of described pin respectively; Described pilot pin is fixedly installed on the outside of a described sidewall and stretches in the described straight trough; The hinged outside, the middle part of described rocking bar at a described sidewall, the two ends of described first connecting rod are hinged on an end of described another hyperbolic axle and the back upper lateral part of described pin respectively, and the two ends of described second connecting rod are hinged on an end of described a pair of bent axle and the upper end of described rocking bar respectively; A straight trough that extends along the direction of motion of described pin is offered in the bottom of described pin, and described rocking bar slightly stretches out described straight trough.

The back-moving spring that a centering block and that can rotate to the rightabout of the direction of motion of described pin resets described centering block is also installed in the lower end of rocking bar of the present utility model, and described centering block slightly stretches out described straight trough.

The utility model has the advantages that owing to adopt hyperbolic axle and planar linkage mechanism the track the when movement locus of pin and human or animal are walked is closely similar; Owing in pin, also be provided with rocking bar, thereby solved the bipod equilibrium problem well, make when a pin is lifted away from ground and still can stand firm; Owing to be provided with a unidirectional centering block, pin can not be retreated or walk about in the original place when walking in the rocking bar lower end.

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described in detail, therefrom can see other advantages of the present utility model.

Fig. 1 is the front view of the walking mechanism of toy of the present utility model;

Fig. 2 is the side view of the walking mechanism of the toy among Fig. 1;

Fig. 3 is the zoomed-in view of " S " portion among Fig. 1.

Now referring to Fig. 1 to 3, the walking mechanism of toy of the present utility model comprises a bearing 1, drive unit 2, transmission device 3, two pin 4,5, a pair of hyperbolic axle 6,7 and pair of links parts 8,9.Bearing 1 has two sidewalls 10,11, and drive unit 2 is a motor 2 by battery 12 power supplies, and battery 12 and motor 2 are arranged in the middle of the two side 10,11 of bearing 1.Transmission device 3 comprises a plurality of transition gears 13,14,15,16, one tooth difference gear group 17, spring leaf 18 and a pair of output gear 19,20, motor 2 is by transition gear 13,14,15 transmissions, one tooth difference gear group 17, spring leaf 18 is arranged on the outside of sidewall 11 and the rotating shaft 21 that its end props up a tooth difference gear group 17, after a tooth difference gear group 17 has been changeed a week, it can break away from engagement with transition gear 15, make both feet motionless, but after tooth difference gear group 17 is rotated further certain angle, be meshed with transition gear again under the effect of spring leaf 18, toy continues again to walk forward.Transition gear 16 is fixed in the rotating shaft 21. Hyperbolic axle 6,7 is arranged on the sidewall 10,11 respectively rotationally and its bent axle partly stretches out outside the sidewall 10,11, two bent axles of each hyperbolic axle 6,7 partly lay respectively at the both sides of the axis of d-axis part, and the d-axis that output gear 19,20 is separately fixed at hyperbolic axle 6,7 is partly gone up and is meshed with transition gear 16.The structure of two linkage components 8,9 is identical, and they are separately positioned on the outside of sidewall 10,11, and the linkage component 8 with sidewall 10 outsides is that example describes here.Linkage component 8 comprises guide rod 22, pilot pin 23, rocking bar 24, first connecting rod 25, second connecting rod 26.Consider the position relation of installation, the extension of axially staggering of (but not must) parallel its underpart can be made in the top of guide rod 22, has vertically an opening straight trough 27 on it; And the middle part of guide rod 22 and lower end are hinged on an end (among Fig. 1 for left end) of hyperbolic axle 6 and the preceding upper lateral part of pin 4 respectively, and pilot pin 23 is installed on the outside of sidewall 10 and stretches in the straight trough 27.The middle part of rocking bar 24 is hinged on the outside of sidewall 10, and the two ends of first connecting rod are hinged on an end of hyperbolic axle 7 and the back upper lateral part of pin 4 respectively, and the two ends of second connecting rod are hinged on the upper end of an end and the rocking bar 24 of hyperbolic axle 6 respectively.Consider the position relation of installation, rocking bar 24 is made bending, but this is not essential.A centering block 28 that can rotate to the rightabout of the direction of motion of pin 4 and the back-moving spring 29 that centering block 28 is resetted are also installed in the lower end of rocking bar 24, and the dotted line among Fig. 3 is the positions of centering block 28 and back-moving spring 29 back pendulum.A straight trough 30 that extends along the direction of motion of pin 4 is offered in the bottom of pin 4, centering block 29 slightly stretches out straight trough 30, so that can contact with ground, when pin 4 has the trend of swing backward, centering block 28 promptly overcomes the elastic force of back-moving spring 29 and swings backward, the bottom surface of pin 4 is contacted with ground, thereby guarantee that pin 4 can not retreat.

When drive motor 2, drive hyperbolic axle 6,7 and rotate synchronously, make pin 4 press the projected path motion by guide rod 22 and first connecting rod 25.Through the meticulous calculation Design to each other part, the track when this track and human or animal are walked is similar.Because two crank portion branches of the first hyperbolic axle 6,7 differ 180 °, therefore when bent axle part the preceding the time, another bent axle part inevitable after, like this because they drive a pin separately, so make a pin preceding, another pin after.When hyperbolic axle 6,7 rotates, the bent axle part that is positioned at the back is with the rotation of hyperbolic axle 6,7 commentaries on classics that makes progress, the company's of making pin thereon forward and be lifted away from ground, at this moment, this pin and another pin are on the same vertical plane, and the rocking bar in it still supports on the ground, to keep the balance of toy, is unlikely to the lopsidedness that lifts to pin.When hyperbolic axle 6,7 is rotated further, this pin gradually forward and drop on the ground, thereby drive bearing 1 forward, rocking bar is and then moved forward.And this moment, another pin then keeps motionless in the original place, the result forms a pin again preceding, another pin after state, so hyperbolic axle 6,7 constantly rotates, and two pin are alternately travelled forward, and forms the action that the human or animal walks.
