Abstract

The utility model relates to a walking toy mechanism, comprising an actuating mechanism, a transmission speed changing mechanism, a control mechanism, an action and walking mechanism and a casing. The fixing point of a walking element and a crankshaft is that the walking element (1) is provided with a traverse strip hole (aan and a mulriple round hole on the center shaft (b); the crankshaft (10) is provided with a step (b) which is fixed with the round hole and a segment (d) which is fixed with the strip hole. The crankshaft is controlled by a cam mechanism to do axial displacement to achieve the changes of the fixing between the step and the round hole, the isolation of the step from the round hole and the fixing between the segment (d) and the strip. The walking toy mechanism breaks the limitation of the prior art of the function of walking in single and straight line, and has the actions of straight walking and turning and becomes more natural.

Description

Walking toy mechanism

The utility model relates to a kind of mechanical Walking toy, especially the four limbs creeping toy.

The mechanical Walking toy of forming by actuating unit (mostly be power supply, motor is constituted), transmission shifting mechanism, controlling organization, action and walking mechanism and shell in the past, its walking part (as leg, foot, pawl etc.) is to be installed in doing on the circular motion section of bent axle with circular hole, and under the driving of bent axle, interlock walking part lower end is made circular motion and finishes to stride forward action.But this structure can only make toy make straight line moving, and can not turn to walking.

The utility model is exactly at the prior art deficiency, and a kind of both straight line movings that provide can turn to the mechanical toy animal of walking.

Mechanical Walking toy provided by the utility model is that walking part (1) is gone up the strip hole (a) that the hole of matching with the section (2) of making circular motion of bent axle changes a horizontal stroke into.The length of this strip hole is the long twice of crank.Walking part (1) is not accepted the component on the fore-and-aft direction that bent axle (10) transmits and is only accepted component on the above-below direction like this, and then walking part (1) moves up and down and is the shape that remains where one is under the effect of the power on the single above-below direction.At this moment as long as the another walking part of symmetry is striding forward action, then toy is just turned to walking part one side that remains where one is.If shorten the angle between strip hole length or change strip hole and the horizontal line, then this walking part will be accepted the component on a part of fore-and-aft direction that bent axle (10) transmits, walking part (1) is small step shape advanced in years under the effect of the component on the fore-and-aft direction of component on whole above-below directions and part.Equally when the walking part of symmetry when striding forward action, toy is just to the walking part one side turning of small step advanced in years.Toy radius of turn under the latter event can be than under the preceding kind of situation big.This strip hole structure makes toy realize turning to the function of walking.

The power that if the walking part is the same with prior art to be accepted bent axle fully and transmitted, then the walking part still strides forward action.For making mechanical Walking toy realize turning to walking, function that again can straight line moving just must make Kong Nengzuo strip hole that the walking part cooperates with bent axle and the variation between the circular hole.The utility model provides following structure simultaneously for this reason.

A compound diameter is greater than the strip hole width on the central shaft of strip hole (a), and the degree of depth (n) does not promptly run through the circular hole (b) of walking part punching place thickness less than this place's wall thickness (m).And the doing on the circular motion section (2) of bent axle, make a step (c) in a side of the compound circular hole of strip hole, this step cooperates with circular hole, promptly its diameter less than circular hole greater than the diameter of the opposite side section (d) of this section (2).Generally circular hole (b) can be compounded in walking part inboard, the circular motion section (2) of doing of bent axle then is provided with step (c) after the length (1) inwards from the outer end.This length (1) often is the wall thickness (m) that preferably equals walking part tapping greater than the degree of depth (n) of circular hole (b).Using a cam (4) to control bent axle (10) directly or indirectly then moves on it is axial.Mobile range be step (c) cooperate with circular hole (b) and step (c) and circular hole (b) break away from but the opposite side section (d) of this section (2) still with two states that strip hole (a) cooperates between distance.Make bent axle when previous state, its interlock walking part of topping bar strides forward motion, and toy is realized straight line moving; And when one state of back, its epimere (d) interlock walking part remains where one is or small step campaign advanced in years, and toy realizes turning to walking.Cam mechanism as this mobile controlling organization, mainly be cylindrical cam (4) and the push rod (8) that is subjected to its promotion, be installed in the step (6) on the push rod (8) and be attached thereto (promptly being subjected to its promotion) and be installed in that step (12) on the bent axle (10) constituted.

Mechanical Walking toy provided by the utility model, the toy of having broken through prior art has only the limitation of straight line moving function, makes to want mechanical Walking toy to realize existing straight line moving action in advancing, and the function that turns to the walking action is arranged again.Make the toy nature that more becomes.

Embodiment:

With the battery is the electronic squirrel toy of power supply, and opening one before it on the left walking part (1) has the strip hole (a) of angle slightly with horizontal line, in walking part inboard, and a compound circular hole (b) on the central shaft of strip hole.By transmission shifting mechanism, its merit after the rotational speed regulation of motor is transferred on the bent axle (10).Circular motion section (2) is made on the left side of bent axle, the remaining length (1) of walking part (1) tapping wall thickness (m) that equals is as section (d) in its outer end, step (c) is made in the inboard, and strip hole and circular hole are made interference fits on this crankshaft section (2) and the walking part.Cam is that cylindrical cam is installed on the camshaft (7), push rod cup (3) is accepted the pressure that cam imposes on, and step (6) is installed on the push rod, and return spring (9) is arranged, push rod (8), camshaft (7) and bent axle (10) are parallel to each other, and all are installed in frame on (5).Be equipped with on the bent axle accept push rod top bar pressure step (12) and return spring (13) is arranged.Rotate by controlling organization driving cam axle (7), when the flange of cam (4) was oppressed push rod cup (3), push rod (8) compressing spring (9) was done displacement, and step (6) discharges step (12).Bent axle is because of spring (13) effect displacement, and this displacement of bent axle is by the scene-affinity restriction of axle sleeve (11).At this moment section (d) still cooperates (as figure four) with strip hole (a) to step (c) with circular hole (b) disengaging.When cam was rotated further release to the compressing of push rod cup (3), spring (9) resetted and makes the push rod displacement, and step (6) is just oppressed step (12) and made spring (13) compression, bent axle (10) displacement.At this moment step (c) cooperates (as figure two) with circular hole (b).In the bent axle displacement, crank section slides in axle housing (14).With this, but the electronic squirrel toy of present embodiment just the time and straight line moving, the time and the walking of turning left.
