ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a remote-control toy car set, and more particularly to a remote-control toy car set, wherein the servo device drives the display to simulate movement of the toy car, so that the user can simulate the instant position lively.
2. Description of the Related Art
A conventional remote-control toy car
100
shown in
FIG. 1
is provided with a camera system
101
mounted in the remote-control toy car
100
.
Referring to
FIGS. 2A and 2B
, the display
102
shows the view
103
before the remote-control toy car
100
, and the view
103
is taken by the camera system
101
.
Referring to
FIGS. 3A and 3B
, the remote-control toy car
100
is rolled and inclined in the clockwise direction “C
1
”. At this time, the camera system
101
is fixed in the remote-control toy car
100
, so that when the remote-control toy car
100
is inclined in the clockwise direction “C
1
”, the camera system
101
is also inclined in the clockwise direction “C
1
”. In such a manner, the view
103
taken by the camera system
101
is inclined in the counterclockwise direction “C
2
” which is opposite to the inclined direction of the remote-control toy car
100
. Thus, when the user sees that the view
103
taken by the camera system
101
is inclined in the counterclockwise direction “C
2
”, the user naturally wishes to control the remote-control toy car
100
to roll in the clockwise direction “C
1
” to compensate inclination of the remote-control toy car
100
, so that the remote-control toy car
100
is further inclined in the clockwise direction “C
1
” and easily falls down or tips over.
SUMMARY OF THE INVENTION
The present invention is to mitigate and/or obviate the disadvantage of the conventional remote-control toy car.
The primary objective of the present invention is to provide a remote-control toy car set, wherein the level indication image is directed toward the inclined direction of the toy car, so that the user can manipulate the toy car to roll in the direction opposite to the inclined direction of the toy car to compensate inclination of the inclined level indication image, so as to guide the toy car to return to the level stable state.
Another objective of the present invention is to provide a remote-control toy car set, wherein the servo device drives the display to simulate movement of the toy car, so that the user can simulate the instant position lively.
In accordance with one aspect of the present invention, there is provided a remote-control toy car set, comprising:
a toy car including:
a body;
a driving device mounted in the body for driving the toy car;
a stabilizer mounted in the body;
a camera system mounted on the stabilizer;
a sensor mounted on the stabilizer; and
a first radio module mounted in the body and electrically connected to the driving device, the camera system and the sensor;
a remote-control device includes:
a servo device;
a display mounted on the servo device;
a remote-control interface; and
a second radio module electrically connected to the display, the remote-control interface and the servo device; wherein:
the user controls the remote-control interface of the remote-control device to control the driving device to drive the toy car to move;
the camera system takes the views on the travel direction to produce a corresponding image signal which is sent to the display which shows the images corresponding to the image signal;
the sensor of the toy car detects movement of the toy car relative to a predetermined fixed direction to produce a corresponding sensing signal and send the sensing signal to the servo device;
the servo device drives the display according to the sensing signal to simulate the movement corresponding to the toy car; and
the stabilizer maintains the plumb direction of the camera system in line with the gravity direction.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
