Abstract

The utility model relates to an electrically driven 'caterpillar' toy, comprising an appearance shell and an internal structure, wherein, the appearance shell is a plastic spiral frame (13) and an appearance skin adhered on the plastic spiral frame; the internal structure comprises a 'foreleg'(10) and a 'hind leg'(2) which are composed of two square boxes and a spring (1) to connect the internal structure. The lower part of the 'foreleg'(10) is provided with four wheels (4), the front axle of the 'foreleg'(10) is provided with a unidirectional rotating gear (3) and a spring (12) and the 'foreleg'(10) is also provided with a power mechanism (19). The 'hind leg'(2) comprises the four wheels (4) in the lower part, a rotating gear (3'), a spring (12') and a battery (E). When opening a power switch, a slide head (15) which is driven by an electric motor moves and makes the direction of electricity change, and then the motion of the 'foreleg'(10) and the 'hind leg'(2) is achieved and the extension and bend moving action of a caterpillar is displayed. The utility model has simple structure and is a lifelike analog worm and an interesting toy for children.

Description

Electrically driven "caterpillar" toy

The utility model is a kind of electronic " caterpillar " toy, belongs to toys.

At present, the toy of selling on the market is a lot of, and great majority are the electric rotary-type toy, and simulation worm mollusk type toy still lacks.

The purpose of this utility model provides the action of a kind of imitation software worm, and it can realize that one stretches " caterpillar " of creeping forward that contract, and makes that children's is interesting recreational stronger.

The utility model is achieved in that the outside framework of being made by plastics, and the profile shell of forming like the crust of worm flexible material is sticked in the outside, and its internal structure has " front foot " " metapedes " and connects reed to be formed." front foot " contains a rectangular box, four wheels is equipped with in the box bottom, and divide two groups, be equipped with on the group wheel shaft wherein and go up control reed of joining on the one-directional rotation gear, connecting one group of ratio wheel by a micromachine in addition and a line rolls the actuating unit of forming, the cotton rope that line rolls on passes central authorities the movable slide head in duct, two knots are arranged on the rope, the motion of this knot can drive slide head, and two sheet metals that are set in its surface can be respectively contacted with corresponding two pairs of contacts near six contacts, cause the conversion of energising direction, in " metapedes " box battery case and battery are housed also, make power connection like this, motor rotates the drive gear and line rolls, make the cotton rope that rolls on receive or put, cause knot to drive pole changer, can realize the wheel turns on " preceding; metapedes " or stop, thereby under the effect of the spring leaf tension force between two " foots ", integral body " caterpillar " is presented in appearance stretch a forward motion that contracts, life-like.

Below with reference to drawings and Examples the utility model is described in further details.

Fig. 5 is the utility model circuit diagram.

Fig. 6 is the utility model profile and action schematic diagram.

Fig. 7 is the utility model " forward and backward foot " one-directional rotation gear schematic diagram.

The utility model comprises profile shell and internal structure two parts composition; 1. the profile shell as shown in Figure 2, one forms outside attaching of spiral framework (13) by plastics or bonding jumper and goes up like worm sample flexible material and painted crust; 2. internal structure as shown in Figure 1, comprises " front foot " (10), " metapedes " (2) and is positioned at the middle microscler reed (1) that plays the connection effect of two foots; " front foot " (10) are rectangular box, four wheels (4) is equipped with in the bottom of box, and be divided into two groups of front and back, on the preceding group wheel shaft one-directional rotation gear (3) is housed, one reed (12) (as Fig. 7) and its joining are arranged on the tooth, but control gear rotates towards a direction, one group of actuating unit (9) also is housed in this square box, as shown in Figure 3, it includes a micromachine (21) and rolls (20) with the one group of ratio wheel (19) and the coupled line that are connected, cotton rope (8) can pass central authorities duct (14) and entity slide head (15) movably, on the cotton rope (8) of its both sides, respectively have a knot (8 ', 8 "); because knot (8 '; 8 ") diameter is greater than duct (14), therefore with moving of line can make knot (8 ', 8 ") drive slide head (15); because there are two corresponding sheet metals (18) that separate on slide head (15) surface, six contacts (16) that make sheet metal (18) and peripheral hardware in moving process are even join A _A1, B _A2Connect or Ab ₁, Bb ₂Connect, and can change the energising direction, thus the rotation of control motor (21); " metapedes " (2) comprise a rectangular box, its bottom sides is equipped with four wheels (4), back group wheel is equipped with the gear (3 ') of one-directional rotation, a reed of last joining (12 ') but control gear is irreversible, also be provided with a battery case internal battery (E) in " metapedes " box, its electric line is to be connected power supply by the middle motor (2) of middle reed (1) and " front foot ".

When operation, connect power switch K pass (6) and see Fig. 6, at this moment K is in contact A .a ₁, B.a ₂As Fig. 4, motor (21) is for just changeing in the connection, and coiling is rolled (20) and begun coiling, because the effect of unidirectional rotating wheel, does not move " front foot " (10) of " worm ", and " metapedes " (2) move forward, and " worm " is by (the F of Fig. 2 ₁) state becomes (F ₂) state, coiling is rolled (20) and is continued coiling, when " worm " is in state (F ₃) time, knot 8 ' drive slide head (15) makes K switch ₁Be on the b contact, i.e. Ab ₁, Bb ₂Connect, motor (21) counter-rotating makes coiling roll (20) beginning unwrapping wire, " worm " begins to uphold under the elastic force effect of reed (1) again, because the effect of unidirectional rotating wheel, " metapedes " (2) of " worm " are motionless, " front foot " (10) move forward, and " worm " at this moment is in state (F ₄), when " worm " upheld to a certain degree, knot 8 " drove slide head (15), it is got back to again on a contact make Aa ₁, Ba ₂Contact, so the individual knot 8 of motor (2) ', the action that moves in circles of slide head (15) parts of etc.ing, and make whole " worm " body occur stretching, in the wrong move and wriggle forward.

The utility model is rational in infrastructure, and simple to operate, interest is by force a kind of toy preferably.
