Description

A kind of bionic walking toy

Technical field

The utility model relates to a kind of for riding riding toy, particularly a kind of bionic walking toy that imitates quadrupeds walking.

Background technology

The type of drive of each type toy of walking for the bionic animal of entertainment for children in prior art is divided into two kinds substantially, and a kind of is electronic, and another kind is manual shake.Generally can only walking or fluctuating swing in original place of electronic class, and because of inside, drive motors and transmission device etc. need be installed, not only complex structure but also profile are heavier, are also not easy to mobile.Manually certain transmission mechanism mode hand with bicyclist or that pin is stepped on of passing through of shake class realizes moving ahead of bionic animal four limbs, and the transmission mechanism of this class bionic toy mainly comprises four limbs, the shell of lying, the shell inside of lying are provided with drive mechanism and drive the driving mechanism of major beat.This class manual bionic toy transmission mechanism and driving mechanism parts are many, and structure is more complicated also, moves ahead for realizing steadily, the processing quality of fit of each parts requires higher, manufacturing cost is also high, and manpower driving effort, is not suitable for especially children and rides and play separately.

Utility model content

The deficiency that the utility model exists for bionic walking toy in prior art, provides a kind of drive mechanism simple, reliable, and cost of manufacture is low, stable drive, operates light bionic walking toy.

The purpose of this utility model is to realize like this, a kind of bionic walking toy, comprise horizontally disposed crossbeam, the front-end and back-end of described crossbeam are fixed with respectively front support axle and rear support axle, the two ends, left and right of described front support axle are hinged with respectively leg one and leg two, the two ends, left and right of described rear support axle are hinged with respectively leg three and leg four, described leg one, leg two, the lower end of leg three and leg four is connected with castor by wheel carrier respectively, described castor is provided with stopping device, described crossbeam middle part is rotatably connected to fork one that can swing, described fork one top and bottom are fixedly connected with respectively upper pendulum bar axle and the draft link axle parallel with rear support axle with front support axle, between described draft link axle left end and leg one, be hingedly connected with connecting rod one, connecting rod two is articulated and connected between described draft link axle right-hand member and leg four, between described upper pendulum bar axle right-hand member and leg two, be hingedly connected with connecting rod three, connecting rod four is articulated and connected between described upper pendulum bar axle left end and leg three, on crossbeam between described front support axle and fork one, be also rotatably connected to fork two, between described fork two one end and fork one, be hingedly connected with the connecting rod five that drives fork one to swing, described fork two other ends are fixedly connected with the folding arm that stretches out crossbeam front end, described folding arm is provided with the manual driving device that can drive folding arm to swing up and down.

Bionic walking toy of the present utility model, while walking forward, drive folding arm and fork two to swing by manual driving device, fork two pulls fork one swing by connecting rod five, fork one drives upper pendulum bar axle and draft link axle sliding and swaying before and after the oscillation center of fork one at two ends, while swing before upper pendulum bar axle is respectively by connecting rod three and connecting rod four driving legs two and leg three-dimensional, drive forward and roll by corresponding castor, meanwhile, draft link axle is driven and is driven leg one and leg four to have the trend swinging backward by connecting rod one and connecting rod two respectively, because stopping device is all housed on castor, therefore swing backward the leg one of trend and leg four as you were and under the effect of oscillatory forces, promote whole device and move forward under the effect of stopping device, so repeatedly alternately drive leg one and leg four synchronously to move ahead by the swing action of fork one or synchronously moving ahead of leg two and leg three realized moving ahead continuously of single unit system.Its walking manner is that the front and back limb of realizing relative angle by swing-bar mechanism alternately synchronously moves ahead, walking and stable drive, reliable, simple in structure, and low cost of manufacture, makes the bionic walking toy of this structure be convenient to promote.

For ease of driving the swing of four limbs, described leg one and leg two are fixed with respectively gangbar one and gangbar two with the upper end of front support axle pin joint, described leg three and leg four are fixed with respectively gangbar three and gangbar four with the upper end of rear support axle pin joint, and described gangbar one end and connecting rod one respective end are articulated and connected and swing and advance around pin joint with driving leg one.

For ease of controlling the amplitude of fluctuation of folding arm, described connecting rod five be articulated and connected fork one below crossbeam and the respective end of fork two, the rearward end of described folding arm is fixedly connected with the respective end of the fork two of crossbeam top, and described folding arm is provided with the adjusting bolt one that can lean respectively with crossbeam and the adjusting bolt two that swing extreme position for spacing folding arm.In this structure, in the time that folding arm is rocked to adjusting bolt one lower end abutment crossbeam upside, fork two is rocked to greatest limit position clockwise, and in the time that folding arm is rocked to adjusting bolt two lower end abutment crossbeam upside, fork two counter-clockwise swings are to extreme position.Can reasonable limits fork one and the swing degree of convergence of fork two by above-mentioned position-limit mechanism, thus the paces that four limbs are steered a steady course rationally controlled, make driving member unbalance stress and transmission not steady to prevent before four limbs that nearly paces are excessive.

For further improving the utility model, described castor excircle is elastomeric material, and castor is rotationally connected by wheel shaft and wheel carrier, described stopping device comprises that swing is connected to the opening drag ring on the wheel carrier of wheel shaft back upper place, two openends of described opening drag ring and the wheel carrier of castor both sides are rotationally connected, and opening drag ring surrounds castor outside, in the time that being rocked to bottom dead centre, opening drag ring retreats with the resilient outer CONTACT WITH FRICTION of castor prevention castor.The opening drag ring of this structure, castor wheel eccentric shaft connects relatively, in the time that castor moves ahead, opening drag ring and wheel rim upwards swing in the effect of gravity and frictional force, do not affect castor and normally move ahead, in the time that castor is wanted to draw back, opening drag ring is sagging under Action of Gravity Field, and castor is blocked, stop castor to rotate backward, thereby realize retaining effect.The stopping device of this structure, simple in structure, light, be skillfully constructed, low cost of manufacture.

For further improving opening drag ring structure, the afterbody ring section of described opening drag ring and wheel rim CONTACT WITH FRICTION is upturned.

For ease of people's manual actuation folding arm of riding, described folding arm external part stretches out to front upper place, and described drive unit comprises that being fixedly installed on folding arm external part also stretches out respectively the handle of the folding arm left and right sides.

For improving bicyclist's comfort level, be fixedly connected with respectively near the left side of leg one and the right side of leg two of described castor top the pedal of stepping on for pin.

For further improving the aesthetics of bionic toy, on described crossbeam, be also provided with support, described support periphery is coated with animal body shell, and described leg one, leg two, leg three and leg are coated with animal foot shell all round week, and the external part before described folding arm is coated with the shell of animal head modeling.
