Abstract

A toy with light emitting function comprises a rope and handles; the rope is transparent and has light emitting diodes (LEDs) inside; a first handle of the handles has a micro generator device connected with the LEDs; the micro generator device comprises a gear assembly and a micro generator motor; an end of the rope is fixedly connected with a first end of a connection member; a second end of the connection member is connected with a dynamic power input end of the gear assembly; the connection member drives the gear assembly to rotate with respect to the first handle along with rotary motion of the rope; a dynamic power output end of the gear assembly is connected with a driving axis of the micro generator motor; an electricity power output end of the micro generator motor is connected with the LEDs.

Claims

1. A toy with light emitting function accomplished by rotary motion of a rope body around a handle comprises a rope and handles connected with the rope, and the rope is transparent and disposed with light emitting diodes (LEDs) inside;

wherein in a first handle of the handles, there is a micro generator device connected with the LEDs inside the rope;

the micro generator device comprises a gear assembly and a micro generator motor;

an end of the rope is fixedly connected with a first end of a connection member;

a second end of the connection member is connected with a dynamic power input end of the gear assembly;

the connection member drives the gear assembly to rotate with respect to the first handle along with rotary motion of the rope;

a dynamic power output end of the gear assembly is connected with a driving axis of the micro generator motor;

an electricity power output end of the micro generator motor is connected with the LEDs inside the rope.

2. The toy as in claim 1, wherein the connection member comprises an “

L”

shaped hard hollow tube.

3. The toy as in claim 2, wherein the connection member also comprises a hard fixing block;

an end of the hard fixing block is fixedly connected with the hard hollow tube, and another end of the hard fixing block is connected with the dynamic power input end of the gear assembly.

4. The toy as in claim 1, wherein the gear assembly is a step-up gear assembly;

the dynamic power output end of the gear assembly is connected with the driving axis of the micro generator motor.

5. The toy as in claim 4, wherein the step-up gear assembly is a 4-stage step-up gear assembly.

6. The toy as in claim 1, wherein the micro generator motor has a rated output voltage of 4.5V.

7. The toy as in claim 1, wherein the electricity power output end of the micro generator motor is connected with two copper contact pieces via two wires respectively;

the two copper contact pieces are fixedly provided inside the first handle;

the two copper contact pieces are not connected with each other;

outer surface of the connection member is symmetrically provided with two arc-shaped copper plates;

the two arc-shaped copper plates are not connected with each other;

one end of each of the two arc-shaped copper plates extends into the connection member;

the connection wires for connecting cathodes and anodes of the LEDs inside the rope extend out from the end of the rope and fixedly connect respectively with portions of the arc-shaped copper plates extended into the connection member;

the two copper contact pieces contact the connection member at opposite positions which are 180 degree apart with respect to each other on the connection member;

when the connection member rotates, the two copper contact pieces intermittently contact with the two arc-shaped copper pieces respectively, so that the LEDs inside the rope are electrically connected with the micro generator motor intermittently.

8. The toy as in claim 2, wherein each of the handles is an assembly of two parts which are assembled together and fixedly connected using screws;

interior part of the first handle is provided with cavities which correspond to positions of the “

L”

shaped hard hollow tube, the gear assembly and the micro generator motor;

shapes of the cavities also correspond to shapes of components to be fitted in so that the components can be securely fixed inside the first handle.

9. The toy as in claim 1, wherein the rope is a soft, transparent and hollow tube;

inside the rope, there is a string of light bulbs constituted by a plurality of the LEDs interconnected via the connection wires.

10. The toy as in claim 1, wherein the toy is a jump rope or a toy meteor hammer.
