Abstract
A toy car includes a car body, a transmission box and a generator device, the generator device has an inductive coil sleeved on a transmission shaft extending outward from the transmission box, and a magnet sleeved on the transmission shaft with respect to the inductive coil. When the transmission shaft rotates, the magnet and the inductive coil are in an opposition movement, which generates electric power to supply load, such as bulbs to produce a lighting effect.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates to a toy car, and more particular to a toy car with a self-generating device to reach a lighting effect of the car.




2. Description of the Prior Art




As shown in

FIG. 4

, a conventional toy car


1


on the market comprises a handle


10


. By rotating the handle


10


, a spindle


11


is linked to rotate and press a spring plate


12


. When the handle


10


is released, the restoring force of the spring plate


12


drives the spindle


11


to rotate, which is meshed with a transmission gear set to drive wheels


14


to roll. Later, an improved toy car has added lights


15


, which requires a battery


16


and a switch


17


to operate and increases the cost.




In view of this, the inventor has invented the present invention to improve the above-mentioned shortcomings.




SUMMARY OF THE INVENTION




It is the primary object of the present invention to provide a toy car, which transforms mechanical energy into electric power, and therefore saves energy and corresponds to environmental protection.




It is another object of the present invention to provide a toy car, which is simple in structure and manpower saving.




It is a further object of the present invention to provide a toy car, which generates a lighting effect to attract a consumer's interest.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




A toy car of the present invention comprises a car body


2


, a transmission box


3


, and a generator


4


.




The car body has a recess


20


in the body and two holes


21


and


22


for transmission shafts


23


and


36


to seat therein, respectively. The transmission shaft


23


is secured with two wheels


24


at respective ends. The car body


2


further comprises headlights


25


and taillights


26


.




A transmission box


3


seats in the recess


20


of the body


2


and comprises a pair of semi-boxes


30


which comprises a spindle


31


with one end secured with a handle


310


. A spring plate


32


and a ratchet gear


33


are sleeved on the spindle


31


in sequence. A transmission gear


34


sleeves on the ratchet gear


33


with a single direction gear


340


meshing with the ratchet gear


33


, which allows one direction only. The transmission gear


34


further meshes with a gear set


35


, and the gear set


35


meshes with a driven gear


360


of a transmission shaft


36


, thereafter. Both ends of the transmission shaft


36


are secured with two wheels


361


.




A generator


4


located next to the transmission box


3


comprises an inductive coil


40


sleeved onto the transmission shaft


36


extending outwardly from the transmission box


30


, electric wires


41


extending from the inductive coil


40


and a magnet


42


. The electric wires


41


are connected to the headlights


25


and the taillights


26


, respectively. The magnet


42


relative to the inductive coil


40


is sleeved on the transmission shaft


36


.




To assemble the present invention, the transmission box


3


is set into the recess


20


of the body


2


, as shown in

FIG. 2

, and then the transmission shafts


21


and


36


are inserted into the holes


21


and


22


, respectively. The electric wires


41


to connected to the headlights


25


and the taillights


26


, and the ratchet gear


33


meshes with the single direction gear


340


of the transmission gear


34


which meshes with the gear set


35


. The gear set


35


then meshes with the driven gear


360


of the transmission shaft


36


.




To operate the present invention, the handle


310


is spun to rotate the spindle


31


and press the spring plate


32


, as shown in FIG.


3


. Due to the ratchet gear


33


on the spindle


31


goes in a single direction, the transmission gear


34


does not follow this movement. When the handle


310


is released, the restoring force of the spring plate


32


brings the spindle


31


to rotate reversely, whereas the ratchet gear


33


on the spindle


31


links the transmission gear


34


, the gear set


35


, the driven gear


360


, the transmission shaft


36


and the wheels


361


to rotate simultaneously. The rotation of the transmission shaft


36


drives not only the rotation of the wheels


361


but also the rotation of the magnet


42


. The magnet


42


on the transmission shaft


36


rotates in a counter direction with respect to the inductive coil


40


to generate electric power. This electric power activates the headlights


25


and the taillights


26


through the electric wires


41


.
