Phenomenon acquires scientific knowledge, does not accomplish to teach through lively activities.
Utility model content
The utility model will solve the above-mentioned problems of the prior art, provide one kind every sky and take electric didactical doll, solve
The problem of the difference of traditional toy science popularization at present, meets the needs of of teaching through lively activities.
The utility model solves the technical solution of its technical problem use: this to take electric didactical doll, including positioning every sky
Plate, hand generator is fixed on positioning plate, and hand generator is connected with the primary for being fixed on positioning back by adverse current device
Coil, lifting is connected with the secondary coil of face primary coil on positioning plate front, and secondary coil output end is connected with positioned at it
One group of warning light at center.After being arranged in this way, DC conversion is exchanged by adverse current device after hand generator hand power
Electricity, alternating current act on primary coil and generate magnetic field, so that secondary coil is generated electric current close to magnetic field and then allow warning light
It shines, the distance between itself and primary coil is adjusted in secondary coil liftable, distance between primary coil and secondary coil
Difference can make warning light luminous intensity generate variation, and the electromagnetic induction that distance more far field generates is weaker, and warning light is darker.Youngster
Child can intuitively see the variation of the phenomenon that electromagnetic induction generates electric current and distance change bring current strength very much, sufficiently
Understand knowledge therein, teaches through lively activities.
As the further improvement of utility model, normal thread is connected with bracket, secondary coil and warning light on positioning plate
It is fixed on bracket, cradle top center is fixed with turning handle by connecting rod.Bracket is used for fixed secondary coil and warning light, passes through
The rotation of turning handle and the cooperation control bracket of screw thread realize elevating function, observe distance difference bring between coils at different levels
Warning light variation.
As the further improvement of utility model, bracket includes central block and outer ring, and outer ring surround central block simultaneously
It is connected by connecting rod, outer ring bottom is equipped with the groove for accommodating secondary coil, is equipped in connecting rod for the recessed of arrangement card line
Slot, warning light are located on central block around connecting rod.Outer ring is connected by connecting rod with central block, is had compared to a monolith plate
Effect reduce weight, holder pivots are more labor-saving, after warning light concentrated setting between can produce concentration effect, more can explicitly feel
Know the variation of luminous intensity, the groove of outer ring and connecting rod bottom can store secondary coil and connecting wire, be conducive to row
Line wiring, simplifies the layout of connecting line, simplifies space.
As the further improvement of utility model, hemispheric transparent protective cover is fixed on positioning plate, protective cover will
Bracket covers on inside, is equipped with the through-hole for accommodating connecting rod at the top of protective cover.Protective cover can play the role of insulation blocking, can be to prevent
Only damage coil and warning light can also be immediately seen the warning light state inside protective cover through transparent protective cover,
Connecting rod, which passes through protective cover, makes turning handle that can also normally manipulate bracket lifting.
As the further improvement of utility model, loudspeaker are fixed on positioning plate, loudspeaker parallel connection accesses hand generator
Electricity-generating circuit.Loudspeaker can play music when hand generator generates electricity, and improve the attraction to children；Loudspeaker parallel connection access electricity
Road will not interfere the normal work of coils at different levels loudspeaker damage, and can bring open circuit when loudspeaker damage if connecting
Risk.
As the further improvement of utility model, warning light is LED light.In view of entire circuit relies on hand generator
Power supply, and the power generation electricity of wireless charging is little, needs using lower-powered warning light, and the power of LED light is low, wireless
Meet the needs of luminous in the generated output of charging, plays good suggesting effect.
As the further improvement of utility model, positioning plate dorsal edge is evenly equipped with one group of support leg, and support leg height is high
In positioning plate behind protruding parts height.Support leg can play a supporting role when laying flat, and can also individually make when placing vertically
For the connecting pin of wall hanging, it is contemplated that positioning plate has some positions outstanding behind, and support leg can play the high positioning plate of frame
Effect, avoids positioning plate from having protruding parts behind and directly contacts with bottom surface, and protection positioning plate has protruding parts behind.
The utility model has the advantages that: the utility model it is structurally reasonable, compact, pass through the hand hair of hand generator
After electricity, DC conversion is alternating current and acts on and then generate magnetic field on primary coil by adverse current device, and secondary coil is close to magnetic
And generating electric current makes warning light shine, intuitively see the phenomenon that electromagnetic induction generates electric current and distance change bring electricity
The variation of intensity of flow fully understands the knowledge of wireless charging, teaches through lively activities.
