Magnetically-actuated toy dolly

The utility model relates to a kind of toy dolly, particularly relates to a kind of magnetically-actuated toy dolly that can promote trolley travelling by magnetic force.

At present, can see various toy dollies on market, these toy dollies are various informative, and structure is different.With regard to type of drive, have manually, electronic, radio or infra-red remote control are also arranged.These traditional type of drive are owing to lack feeling of freshness by people are common.And from structure, the structure of most of toy dollies all is non-removable stationary structure, these stationary structures make children can't take action on one's own to carry out dismounting, thereby can not satisfy the curiosity of children to the dolly internal structure, are unfavorable for developing children's manipulative ability and intelligence.In addition, people are not used as magnetic force the driving force of toy dolly as yet up to now, thereby the present toy dolly that does not still have magnetically-actuated emerges.

It is a kind of by magnetically-actuated that the purpose of this utility model is to provide, but sounding, luminous and easy-disassembling-assembling magnetically-actuated toy dolly during operation so that improve the interest that children play with toys and start the dismounting ability, and help children's intellectual development.

For achieving the above object, the utility model provides a kind of magnetically-actuated toy dolly, this dolly comprises front truck wheels 2 and the rear wheel group 3 that is contained in car body 1 bottom, it is characterized in that, in a pair of wheel 21,22 of described front truck wheels luminous, sound-producing device 4 is housed, in a pair of wheel 31,32 of rear wheel group one first magnetic column 5 is housed respectively, and this dolly also is provided with a handgrip 6 that separates use with above-mentioned two set of wheels, and an end end of handgrip is equipped with and is driven second magnetic column 7 that first magnetic column is used.

Described luminous, sound-producing device 4 comprises buzzing sheet 41, light emitting diode 42, trigger switch 43 and battery 44, wherein buzzing sheet, trigger switch and battery are contained on the wiring board 45, two light emitting diodes then are contained in the outside of a pair of wheel 21,22 of front truck wheels, and link to each other with wiring board with lead; Described trigger switch is in the metal switch cover 431 on being fixed in wiring board a live metal short column 432 to be housed, a side opening of switch cover, and its openend front portion is equipped with a metal and is triggered sheet 433, and an end that triggers sheet is connected with wiring board.

Described wheel the 21, the 22nd fastens the hollow wheel that forms by the two halves hub of symmetry, and luminous, sound-producing device 4 is housed in it, and there is a wheel shaft 211 of one with it wheel 21 inboards, are with another wheel 22 on the wheel shaft; Described wheel 31,32 also is to fasten the hollow wheel that forms by the two halves of symmetry, the opposite polarity end adhesive of one first magnetic column 5, two wheels by its magnetic column respectively is housed in the car body both sides in it

Described handgrip 6 is Y shape or U-shaped, and one second magnetic column 7 respectively is equipped with at its openend both ends.

When being at play this magnetically-actuated dolly, handgrip 6 near rear wheels 31,32, is utilized wheel to repel each other with magnet opposed polarity on the handgrip or inhales principle mutually, promote wheel and rotate, and make the circuit connection by trigger switch.The moving of car while, luminous, sound-producing device flashes and musical sound.

The utility model has changed the type of drive of traditional toy dolly,, can make children have certain feeling of freshness, and obtain enjoyment from play as driving force with magnetic force, can make them understand the ABC of relevant magnetic force again.Simultaneously, because wheel of the present utility model adopts manner to be connected, and adopt magnetic attracting to be connected with nested between wheel and the wheel, therefore can arbitrarily carry out dismounting, children can therefrom improve manipulative ability, and satisfy their curiosity.Dolly can be sounded and glisten when operation, thereby can excite children's game interest more.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 has provided overall structure of the present utility model, and by diagram, the utility model comprises car body 1, front truck wheels 2 and rear wheel group 3, and is provided with a handlebar 6 that separates use with car body and wheel.

Above-mentioned car body 1 is that it can have multiple moulding, and is as various vehicles, animal-shaped etc. by plastics, cardboard or metal lamellar car body.The hole that has two installation wheels to use in the car body bottom is equipped with front truck wheels 2 and rear wheel group 3 respectively in the hole.

Front truck wheels 2 are made up of wheel 21,22, and its structure can be referring to Fig. 3, and they are to fasten the hollow wheel that forms by the two halves hub of symmetry, and the two halves hub can adopt multiple structure to be interlocked.In this example, the two halves hub is interlocked by the convex-concave button at its edge.In wheel 21 inboards a wheel shaft 211 of one is with it arranged, be with another wheel 22 on the wheel shaft.Wheel 21,22 is socketed on the car body both sides by wheel shaft 211.Luminous, sound-producing device 4 is housed in above-mentioned two wheels, this device comprises buzzing sheet 41, light emitting diode 42, trigger switch 43 and battery 44, wherein buzzing sheet, trigger switch and battery are contained on the wiring board 45, two 42 of light emitting diodes are contained in the outside of wheel 21,22, and link to each other with wiring board with lead.Described trigger switch structure and duty such as Fig. 3, Fig. 5, shown in Figure 6, it is in the semicircular metal switch cover 431 on being fixed in wiring board a metal short column 432 to be housed, this short column can move in metal cap vertically, the switch cover bottom is welded on the wiring board, the one side opening, one metal is housed in its openend front portion triggers sheet 433, an end that triggers sheet is welded on the wiring board.When wheel rotates, metal short column 432 gravitates move to openend in switch cover, and skid off switch cover and trigger sheet 433 with metal and contact (referring to Fig. 6), because its other end contacts with the metal switch cover, therefore form short circuit, circuit is triggered and is connected, and diode flashes, and the buzzing sheet sends musical sound.Each element of this device can adopt simple custom circuit to be formed by connecting.

Rear wheel group 3 is made up of wheel 31,32, its structure as shown in Figure 4, they also are to fasten the hollow wheel that forms by the two halves of symmetry, its fastening structure is to be provided with two inserting columns 311 in the inboard of half hub, second half hub inboard is provided with two spliced eye seats 312, cooperates with the grafting of spliced eye seat the two halves hub to be fastened by inserting column to be one.One first magnetic column 5 respectively is housed in the wheel 31,32, and this magnetic column places in the circular groove of two hub central authorities versatilely, makes it do the time spent at the magnet that is subjected on the handlebar 6, and wheel can rotate around it.Two wheels pass through an opposite polarity end adhesive of its magnetic column in the car body both sides.

Handlebar 6 is Y shape or U-shaped, and its openend both ends respectively are inlaid with one second magnetic column 7, is used to drive two first magnetic columns 5 on the rear wheel.Handlebar 6 is parts that are separated with car body and wheel.During use, it near rear wheel, if second magnet of its end is identical with the first magnet polarity on the rear wheel, then owing to promoting dolly, homopolar-repulsion is advanced; Make the second magnet polarity opposite if it is turned over a face, then can haul dolly and walk because heteropole is inhaled mutually with magnet polarity on the rear wheel.

The wheel and the handgrip of this magnetically-actuated toy dolly are made by non-magnet material, select for use typical non-magnet material plastics to make in this example.
