Abstract

Disclosed is a motorless electric toy, including a shell and an action piece which is arranged in the shell, wherein, a pedestal is arranged in the shell; an electromagnetic device is arranged between the pedestal and the action piece; the electromagnetic device includes a coil framework, a coil and a permanent magnet; the coil is coiled on the coil framework and connected with a drive circuit; one end of the permanent magnet is extended into the coil framework; a spring is nested on the permanent magnet and arranged between the wall of the coil framework and a position-limiting seat; the permanent magnet and the coil cooperate with each other. The invention has the advantages that the traditional drive structure which mainly includes a motor and a gear is rejected by the electric toy and replaced with the novel action piece driven by the electromagnetic device; the drive is generated completely by the magnetic induction, so that the energy loss caused by the action conversion between the motor and the gear device can be avoided. Thereby, the electromechanical conversion efficiency is improved and the electricity is saved.

Description

A kind of no motor-driven electronic toy

Technical field

The present invention relates to a kind of toy, especially relate to a kind of no motor-driven electronic toy.

Background technology

As everyone knows, the structure of electronic toy in the past mainly comprises the gear mechanism of battery, motor and a plurality of gears engaged, its operation principle is that the electric energy in the battery drives dc motor work, dc motor driven gear mechanism rotates, a plurality of gear meshing are to be used for turning down the needs that speed that gear rotates adapts to toy, act on the action part of toy again by wheel or bar, make toy have innervation, attract liking of children with this.There are this some problems in the toy of this structure, because in this a series of electricity one mechanical switch process, the cooperation of each mechanical part all exists friction, and the mechanical realization complexity of electronic toy, parts inertia in course of action is very big, can not be in the conversion of moment execution, therefore exist bigger energy loss, make the service life of battery shorter, installation makes motor and more gear also make existing toy volume bigger in toy, and its production cost is higher.

Summary of the invention

Technical problem to be solved by this invention provides that a kind of power consumption is little, profile is exquisite, lower-cost no motor-driven electronic toy.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of no motor-driven electronic toy, comprise the movable action piece that is provided with in housing and the housing, be provided with pedestal in the described housing, be provided with electromagnetic mechanism between described pedestal and the described action piece, described electromagnetic mechanism comprises coil rack, coil and permanent magnet, described coil is on described coil rack, described coil is electrically connected with drive circuit, one end of described permanent magnet stretches into described coil rack, be arranged with spring on the described permanent magnet, described spring is between described coil rack wall and limit base, and described permanent magnet and described coil cooperatively interact.

Described drive circuit comprises power switch, Music Clip, the first transistor and transistor seconds, first pin of Music Clip is connected with the colelctor electrode of the first transistor by oscillation resistance, the 3rd pin of Music Clip is connected with the emitter stage of the first transistor, be provided with second resistance between the base stage of described the first transistor and the colelctor electrode, second pin of described Music Clip is connected with the colelctor electrode of the first transistor and the emitter stage of transistor seconds respectively, between the emitter stage of described the first transistor and the base stage piezoelectric patches is set, the 4th pin of described Music Clip is connected with the base stage of described transistor seconds, described power switch is connected with the 7th pin of Music Clip by filter capacitor, the 7th pin ground connection of described Music Clip, described coil one end is connected with power switch by described filter capacitor, the other end of described coil is connected with the colelctor electrode of transistor seconds, described transistor seconds is respectively by the 3rd resistance, the LED group is connected with Switching Power Supply with described filter capacitor, and the 5th pin of described Music Clip is connected with the two ends of loudspeaker respectively with the 6th pin.

Described permanent magnet is fixed on the described limit base, and described action piece is fixed on the described coil rack.

Described coil rack is fixed on the described pedestal, and described action piece is fixed on the described permanent magnet.

Described LED group comprises LED1 and LED2.

Compared with prior art, advantage of the present invention has been abandoned traditional dynamic structure two big parts in electronic toy be motor and gear, replace with the electromagnetic mechanism drive actions part of novelty, be to produce power fully by magnetic induction, avoided the energy loss of action conversion between motor and the gear mechanism, an electric mechanical switch efficient is improved, relatively power saving.

The present invention has save in whole transmission device and accounted for most motor of cost and gear-box, and is alternative with the magnet and the coil of cheapness, reduced production cost.Because the structure of electromagnetic mechanism is comparatively simple, reduced the volume of toy, reduced the cost of shell.

Electromagnetic mechanism is by the audio chip control of drive circuit, verily reduce the action command of chip, so conversion efficiency height, power consumption economizes, and can realize exercises neatly, need not redesign gear and lever when needs change action, and as long as in chip, import the signal of telecommunication of different simulated action, can realize the variation of moving, very convenient, increased the interest and the diversity of toy gift.As the audio signal of importing song can make toy obtain the action synchronous with song.

The specific embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

Embodiment one: a kind of no motor-driven electronic toy, comprise the movable action piece 2 that is provided with in housing 1 and the housing 1, be provided with pedestal 3 in the housing 1, be provided with electromagnetic mechanism between pedestal 3 and the action piece 2, electromagnetic mechanism comprises coil rack 4, coil 5 and permanent magnet 6, coil 5 is on coil rack 4, coil 5 is electrically connected with drive circuit by copper cash 9, one end of permanent magnet 6 stretches into coil rack 4, be arranged with spring 7 on the permanent magnet 6, spring 7 is between coil rack 4 walls and limit base 8, and permanent magnet 6 cooperatively interacts with coil 5, permanent magnet 6 is fixed on the limit base 8, and action piece 2 is fixed on the coil rack 4.Drive circuit comprises power switch SW, model is the Music Clip of SDS63H, the first transistor V1 and transistor seconds V2, first pin of Music Clip is connected with the colelctor electrode of the first transistor V1 by oscillation resistance R1, the 3rd pin of Music Clip is connected with the emitter stage of the first transistor V1, be provided with second resistance R 2 between the base stage of the first transistor V1 and the colelctor electrode, second pin of Music Clip is connected with the colelctor electrode of the first transistor V1 and the emitter stage of transistor seconds V2 respectively, piezoelectric patches D is set between the emitter stage of the first transistor V1 and the base stage, the 4th pin of Music Clip is connected with the base stage of transistor seconds V2, power switch SW is connected with the 7th pin of Music Clip by filter capacitor C1, the 7th pin ground connection of Music Clip, coil L1 one end is connected with power switch SW by filter capacitor C1, the other end of coil L1 is connected with the colelctor electrode of transistor seconds V2, transistor seconds V2 is respectively by the 3rd resistance R 3, the LED group is connected with Switching Power Supply with filter capacitor, the LED group comprises LED1 and LED2, and the 5th pin of Music Clip is connected with the two ends of loudspeaker Y 1 respectively with the 6th pin.
