DETAILED DESCRIPTION OF THE INVENTION
[0026] In order to clearly understand the technical features,
purpose and effect of the present invention, embodiments of the
present invention are illustrated in details with accompanying
diagrams.
[0027] As shown in FIG. 1, in a preferred embodiment of the present
invention, a tracking toy vehicle may identify a tracking line S
previously drawn and set under the tracking car, and the toy
vehicle may be controlled to move along the tracking line S. In
other embodiments, the tracking line S may also by formed by a
bendable soft line body.
[0028] In the description of the toy vehicle of the present
invention, it needs to understand that, orientation or positional
relationship instructed by the terms "front", "rear", "up", "down",
"left", "right" is based on orientation or positional relationship
shown in figures, which is only used to conveniently describe the
present invention and simply illustration, not to instruct or
intimate that the device or element must have particular
orientation, be composed and operated in particular orientation.
Thus, it cannot be understand as limiting the present
invention.
[0029] In some embodiments, a tracking toy vehicle includes a
vehicle body 1, a left drive wheel 2, a right drive wheel 3, a
sensing device 4 installed at bottom of the vehicle body 1 for
sensing a tracking line S, a controller electrically connected to
the sensing device 4, a light source 5 installed at bottom of the
vehicle body 1 for lighting the tracking line S under the vehicle
body 1, a left driving device 6 for driving the left drive wheel 2
to steer, and a right driving device 7 for driving the right drive
wheel 3 to steer.
[0030] In some embodiments, the sensing device 4 includes a first
sensor 41 and a second sensor 42 respectively installed on left and
right sides of an axle of the car body, for respectively sensing
whether the location is corresponded to or deviated from the
tracking line S. Further, the first sensor 41 and the second sensor
42 are symmetrically set on two sides of a longitudinal centerline
of the vehicle body 1 and near a front end of the vehicle body 1,
so that there is enough time for the toy vehicle to steer and it
may be easily controlled by users. Preferredly, the first sensor 41
and the second sensor 42 are photosensitive diodes, so as to
determine whether the location is corresponded to or deviated from
the tracking line S through the tracking line S and light variation
around. Of course, in other embodiments, the first sensor 41 and
the second sensor 42 may also be Infrared sensors.
[0031] When using the toy vehicle, first, a user installs the first
sensor 41 and the second sensor 42 on the top of two sides of the
tracking line S respectively. The toy vehicle moves straight
initially when the toy vehicle normally moves forwards or
backwards. If the tracking line S is a curve, the first sensor 41
or the second sensor 42 is corresponded to the curved tracking line
S below and senses the tracking line S, and sends signals to the
controller, the controller sends control signals to the left
driving device 6 or the right driving device 7. The toy vehicle
steers by modulating the rotational speed of the left drive wheel 2
or the right drive wheel 3, so that the first sensor 41 and the
second sensor 42 are maintained on two sides of the tracking line
S, and the toy vehicle moves along the direction of the tracking
line S. When the toy vehicle runs too fast that passing the
tracking line S, the controller sends control signals to let the
toy vehicle drives back to the area of the tracking line S. When
the toy vehicle hits objects in driving, the controller is able to
send control signals to let the toy vehicle drive in the opposite
direction.
[0032] In some embodiments, the first sensor 41 is electrically
connected to the left driving device 6 through the controller, to
control the rotational speed of the left driving device 6 through
sensing signal of the first sensor 41; the second sensor 42 is
electrically connected to the right driving device 7 through the
controller, to control the rotational speed of the right driving
device 7 through sensing signal of the second sensor 42.
[0033] For example, when the first sensor 41 senses the tracking
line S, it means that the wheel on the left side of the vehicle
body may nearly touch the tracking line S. The controller may
control the left driving device 6 to reduce the rotational speed of
the left drive wheel 2, so that the toy vehicle is able to steer
left. When the second sensor 42 senses the tracking line S, it
means that the wheel on the right side of the vehicle body may
nearly touch the tracking line S. The controller is able to control
the left driving device 7 to reduce the rotational speed of the
right drive wheel 3, so that the toy vehicle can steer right.
[0034] In other embodiments, the first sensor 41 is electrically
connected to the right driving device 7 through the controller, to
control the rotational speed of the right driving device 7 by
sensing signals of the first sensor 41; the second sensor 42 is
electrically connected to the left driving device 6 through the
controller, to control the rotational speed of the left driving
device 6 by sensing signals of the second sensor 42. For example,
when the first sensor 41 senses the tracking line S, it means that
the wheel on the left side of the vehicle body may nearly touch the
tracking line S. The controller is able to control the right
driving device 7 to improve the rotational speed of the right drive
wheel 3, so that the toy vehicle is able to steer left. When the
second sensor 42 senses the tracking line S, it means that the
wheel on the right side of the vehicle body may nearly touch the
tracking line S. The controller may control the left driving device
6 to improve the rotational speed of the left drive wheel 2, so
that the toy vehicle can steer to right.
[0035] Further, the light source 5 is set at bottom of the vehicle
body 1 to irradiate the tracking line S, so that the tracking line
S can be easily sensed by photosensitive diodes. The light source 5
includes a first infrared light 51 and a second infrared light 52
symmetrically set on the two sides of the longitudinal centerline
of the vehicle body 1, the first infrared light 51 and the second
infrared light 52 are set near the first sensor 41 and the second
sensor 42 respectively. The light source 5 may be able to remove or
be closed through a switch when the ambient light is strong enough
that the tracking line S can be easily identified or when the
tracking line S itself is bright.
[0036] In some embodiments, the left driving device 6 further
includes a left motor 61 and a left gear set 62 installed between
the left motor 61 and the left drive wheel 2, the left gear set 62
are respectively engaged with an output shaft of the left motor 61
and an axle of the left drive wheel 2, so that the rotational speed
ratio of the left motor 61 and the left drive wheel 2 is
applicable.
[0037] The right driving device 7 further includes a right motor 71
and a right gear set 72 installed between the right motor 71 and
the right drive wheel 3, the right gear set 72 is respectively
engaged with an output shaft of the right motor 71 and an axle of
the right drive wheel 3, so that the rotational speed ratio of the
right motor 71 and the right drive wheel 3 is applicable. The left
gear set 62 and the right gear set 72 may be removed if the output
speed of the left motor 61 and the right motor 71 is lower.
[0038] Preferredly, the light source 5 further includes a third
infrared light 53 set on the longitudinal centerline of the vehicle
body 1, the third infrared light 53 is located between the first
infrared light 51 and the second infrared light 52, the sensing
device 4 further includes a third sensor 43 set on the longitudinal
centerline of the vehicle body 1, the third sensor 43 is a
photosensitive diode and located between the first sensor 41 and
the second sensor 42, the third sensor 43 is electrically connected
to the left driving device 6 and the right driving device 7 through
the controller.
[0039] While the toy vehicle moves, the third sensor 43 and the
third infrared light 53 are located above the tracking line S. If
the tracking line S is straight, the third sensor 43 can generate a
relatively stable resistance. The controller receives the signal
and simultaneously sends the same circuit to drive the left driving
device 6 and the right driving device 7 to move synchronously, so
that the toy vehicle does not wobble in order to provide stability
when running straight.
[0040] A power supply slot 11 provided for power supply
installation is set on the vehicle body 1, multiple touch points
set on the power supply slot 11 are provided to be electrically
connected to the light source 5, the left motor 61 and the right
motor 71 respectively. In other embodiments, power source may be a
built-in setting electrically connected to the light source 5, the
left motor 61 and the right motor 71.
[0041] The tracking toy vehicle further includes a speaker 12, the
speaker 12 is electrically connected to the controller, and the
speaker 12 may sound different sounds to improve entertainment.
[0042] It can be understand that the above technical features may
be combined as desired without restriction.
[0043] All the above are only the embodiments of the present
invention; it is not intended to limit the scope of the present
invention. All the equivalent structure or process transformation
used description and accompanying drawings of the present
invention, or those directly or indirectly applied the present
invention in other relevant technical field are included in the
