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.

is an exploded view of the present invention;
FIG. 2
is a perspective view of the present invention;
FIG. 3
is a view showing operating the toy car incorporated with the present invention; and
FIG. 4
is a top view of a prior toy car.
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
.
