ABSTRACT:
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.
