Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a mounting bracket
structure of remotely controllable toy rally car. The mounting
bracket structure includes intersecting linkages and assistant
rebounding shock-absorbers which are connected between the mounting
bracket and the front and rear support racks to support the
mounting bracket. The mounting bracket has increased height and is
adapted to varied road configurations. The mounting bracket itself
has a resilient shock-absorbing ability against lateral tilting so
that the toy rally car can run more stably under poor road
condition.
[0002] The existent conventional remotely controllable model cars
carry various kinds of equipments which simulate the parts of a
real car. It is known that a model car has a not so heavyweight.
Referring to FIG. 6, with respect to a four-wheel model car, the
mounting chassis 70 is made of a panel with large area. The gap
between the chassis 70 and the wheels 71 is very short so that the
buffering distance is quite limited. As a result, even though the
model car is equipped with shock-absorbers 72, It is hard to
achieve a satisfactory buffering effect. Therefore, in case the
wheels of the model car hit alien objects or the model car turns
abruptly and the car body suffers a shock or centrifugal force, the
shock-absorbers often fail to provide sufficient buffering effect
and all the shock-absorbers and the entire mounting structure
(including chassis 70) will jump in accordance with the change of
road configuration. In order to more stabilize the gravity center
of the car body, the chassis 70 is often such designed as to be
lower. This makes the buffering space more reduced. In case of an
abrupt or irregular road face, the existent model car with the
conventional shock-absorbers can hardly stably run on the road and
may turn over due to excessively great shock. Therefore, it is
necessary to provide an improved mounting bracket structure for
remotely controllable model car to enhance the shock-absorbing
ability and stability thereof in running.
SUMMARY OF THE INVENTION
[0003] It is therefore a primary object of the present invention to
provide an improved mounting bracket structure of remotely
controllable toy rally car, which provides double shock-absorbing
structures between the mounting bracket and the front and rear
support racks. The mounting bracket structure includes a mounting
bracket, intersecting linkages, rebounding shock-absorbers and
front and rear support racks on which wheels are mounted. The
mounting bracket includes at least two lateral supports racks. Each
intersecting linkage includes two intersecting links. The
intersecting linkages are connected between the bottom side of the
mounting bracket and the front and rear support racks near the
gravity center of the mounting bracket so as to concentratively
support the mounting bracket. The rebounding shock-absorbers are
bridged between outer ends of the lateral support racks and the
outer ends of the intersecting linkages. The height of the mounting
bracket is increased and the mounting bracket itself is adapted to
poor road condition and has a resilient shock-absorbing ability
against lateral tilting to assist the shock-absorbers disposed
between the wheels and the front and rear support racks. Therefore,
when running on a road with poor road face, the toy rally car can
still run stably without possibility of over-shocking or lateral
tilting.
[0004] The present invention can be best understood through the
following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] Please refer to FIGS. 1, 2 and 3. The mounting bracket
structure of remotely controllable toy rally car of the present
invention includes a mounting bracket 1, intersecting linkages 2
and rebounding shock-absorbers 3. The mounting bracket 1 is
composed of two lateral supports racks 11, 12 (substantially
V-shaped rack bodies) and a seat board 13 retained by the lateral
support racks 11, 12. The mounting bracket 1 defines an internal
space in which a transmission and power supply (not shown) are
mounted. Each of the intersecting linkages 2 is composed of two
intersecting links for supporting the mounting bracket 1. One end
of each intersecting linkage 2 is connected to the mounting bracket
I between the lateral support racks 11, 12 near the gravity center
of the mounting bracket 1. The other end of the intersecting
linkage 2 is respectively locked on a front and a rear support
racks 41, 42 on which wheels 5 are mounted. Accordingly, the
arrangement serves to concentratively support the mounting bracket
1 at the gravity center thereof. One end of each intersecting
linkage 2 is fixed on the fixing rods 122 connected between the
locating holes 121 of the bottoms of the lateral support racks 11,
12. Therefore, the intersecting linkages 2 are positioned near the
gravity center of the mounting bracket. The other end of the
intersecting linkage 2 is fixed on the front and rear support racks
41, 42 of the car body 4, whereby the intersecting linkages 2 serve
to provide a supporting force arm for the mounting bracket 1. In
addition, the end sections of the rebounding shock-absorbers 3 are
respectively bridged between outer ends of the lateral support
racks II, 12 and the outer ends of the intersecting linkages 2. The
front and rear sides of the lateral support racks 11, 12 are formed
with adjustment holes 131. The front and rear support racks 41, 42
are correspondingly formed with through holes 411, 421. The
rebounding shock-absorbers 3 are respectively bridged between the
adjustment holes 131 and the through holes 411, 421. Therefore, the
rebounding shock-absorbers 3 are bridged between the outer ends of
the lateral support racks 11, 12 and the outer ends of the
intersecting linkages 2. This increases the height of the mounting
bracket 1 and the mounting bracket 1 itself has a resilient
buffering ability between the mounting bracket 1 and the front and
rear support racks 41, 42 so as to absorb the shock caused by poor
road condition or lateral tilting. Accordingly, in running, the
shock-absorbing ability of the mounting bracket 1 is enhanced to
assist the shock-absorbers 6 disposed between the wheels 5 and the
support racks 41, 42.
[0013] Please refer to FIGS. 4 and 5. According to the above
mounting bracket structure of the present invention, the mounting
bracket 1 and the front and rear support racks 41, 42 are supported
in a buffered state. In the case that the wheels 5 mounted under
the support racks 41, 42 are shocked by alien objects, the shock is
first absorbed by the shock-absorbers 6 mounted between the front
and rear support racks 41, 42 and the wheels 5. In case the
shocking force exceeds a certain value which the shock-absorbers 6
can hardly bear, the excessive shocking force can be further
absorbed by the rebounding shock-absorbers 3. Therefore, the
mounting bracket 1 can keep stable during running. Moreover, in the
case that the car body is laterally tilted due to centrifugal force
in turning, the intersecting linkages 2 connected between the
mounting bracket 1 and the front and rear support racks 41, 42 can
cooperate with the rebounding shock-absorbers 3 for providing an
offsetting torque. This provides the mounting bracket 1 with an
anti-lateral tilting or anti-lateral deflection effect. Therefore,
the toy rally car is better adapted to poor road condition and has
better running ability.
[0014] The above embodiment is only used to illustrate the present
invention, not intended to limit the scope thereof. Many
modifications of the above embodiment can be made without departing
from the spirit of the present invention.
