Mobile Phone Patent Description
BACKGROUND OF THE INVENTION
I. Field of the Invention
This invention relates to a fixed base assembly of mobile phones.
II. Description of the Prior Art
In the fast changing and highly efficient environment nowadays,
electronic communications products (such as a mobile phone) have
become a convenient and efficient communications tool. Since mobile
phones are usually placed at a position according to the user's
need (such as being hung at the user's waist or neck, or put in
a backpack, a bag, or a car, etc.) and such position varies with
the actual situation, therefore, it generally requires a fixed base
to fix the mobile phone. In the example of putting the mobile phone
in a car, the mobile phone is clamped and fixed to one end of a
clamping base of the fixed device, and the other end of the fixed
device is disposed at an appropriate position in the car, so that
the driver can feel relieved and concentrate on driving.
However, since there are various designs for the fixed device of
mobile phones in the market, therefore a prior-art fixed device
which can be attached onto any fixed object in the car (such as
a drink holder or a car window, etc) is used for example. Please
refer to FIGS. 1 and 2 for the prior-art fixed device. Such fixed
device 10 has a base 11 which is a cone symmetrical along the circumference
and comprises a hollow cylinder 12 extended upward from the center
of the top of the base 11, and a pair of corresponding small and
large apertures 121, 122 respectively extended upward from the cylinder
12 and the cone, and the bottom of the cone is hollow, and a stop
rod 123 is disposed at the bottom of the large aperture 122 in the
cylinder 12 (as shown in FIG. 2).
Further, the hollow of the bottom of the cone allows the base 11
to be movably coupled to a sucking disc 13, and the diameter of
the sucking disc 13 is slightly larger than or equal to the external
diameter of the bottom of the base 11. A bar-shaped pillar is extended
upward from the center of the bar-shaped pillar 131, and a channel
132 is disposed on the pillar 131 such that the stop rod 123 in
the bottom of the base 11 can be guided into the channel 132 to
successfully slide the base 11 onto the sucking disc 13 (as shown
in FIG. 2), and the outer periphery of the bar-shaped pillar 131
is surrounded by a spring 133.
Further, there is a clicking member 14, which has a head section
141 to be extended into the large aperture 122 of the cylinder 12
and the channel 132 of the pillar 131 of the sucking disc 13, and
pivotally coupled to the small aperture 121 by a peg 15. One end
of the cylinder 12 of the base 11 is coupled to a connecting rod
16, and the other end of the connecting rod 16 is disposed on a
clamping base 161 which is used for clamping the mobile phone.
Therefore, if the exposed end 142 of the clicking member 14 is
pressed as shown in FIG. 2, the head section 141 presses against
the stop rod 123 to compress the spring 133 such that the hollow
at the bottom of the base 11 presses on the sucking disc 13 to constitute
a vacuum and attaches the bottom of the base 11 onto the sucking
disc 13 tightly. The sucking disc 13 will contract inward as the
hollow at the bottom of the base 11 is attached by the sucking disc
13 and the sucking disc is further attached securely onto any fixed
object 17 in the car. On the other hand, if the exposed end 142
of the clicking member 14 is lifted such that after the force of
the head sections 141 pressing against the stop rod 123 is gone,
the bottom of the base 11 is lifted and separated from the sucking
disc 13 due to the resilience of the spring 133. Therefore, the
fixed device 10 can be removed successfully.
Although the way of using the base 11 and the sucking disc 13 of
the fixed device 10 to work together with the clicking member 14
can attach the sucking disc 13 securely onto a fixed object 17 and
fix the mobile phone onto another end of the fixed device 10, the
structures of the large aperture 122 on the cylinder 12 of the base
11, the stop rod 123 at the bottom and the sucking disc 13 of the
pillar 131, the channel 132 on the pillar 131, and the clicking
member 14, etc not only are complicated, but also carry a high manufacturing
cost, and make the overall assembling very complicated and laborious.
Furthermore, the clicking member 14 will break easily when it has
been used for a long time, and has the shortcomings of causing the
base 11 unable to operate and to be attached to the sucking disc
13. Therefore, it has a poor stability which definitely affects
the utility of the fixed device 10.
SUMMARY OF THE INVENTION
In view of the shortcomings of the aforementioned conventional
fixed device which has a base, a sucking disc, and a clicking member,
etc. on one end including the complicated structure, high mold manufacturing
cost, overall complicated assembling procedure, easily broken clicking
member, and inoperable base and sucking disc, etc, the inventor
of the present invention based on years of experience and technologies
in the mobile phone earphone industry, and conducted extensive researches
and experiments to solve the problems and overcome the shortcomings,
and finally invented the "Fixed base of mobile phone"
in accordance with this invention. By this invention, the aforementioned
shortcomings of the prior can be overcome.
The primary object of the invention is to provide a mobile phone
fixed base with simple structure, easy-to-make mold, fast assembling,
and low cost features. The fixed base comprises a base having a
cylinder at the center of the base, a hollow at the bottom of the
base being connected to the cylinder such that the base is sheathed
into a pillar at the center of a sucking disc, a spring surrounding
the periphery of the pillar such that the base can expand and contract
along the pillar and allowing a rotary member to be disposed on
the cylinder and an extended position of the base, a flange substantially
having a wave-shaped height and being symmetrical along the periphery,
such that the two flanges respectively have a wave valley and a
wave peak, a peg being used to be inserted into a pair of corresponding
rectangular apertures of the cylinder to pivotally couple the sucking
disc pillar, rotary member, and base, and both ends of the peg being
exposed from the flange. If the fixed base is fixed onto a fixed
object, the rotary member is rotated to move both ends of the peg
along the wave valley and wave peak of the flange, so that the bottom
of the base presses against the sucking disc to constitute a vacuum
condition and attaches the base onto the fixed object, or lifts
the sucking disc to separate the sucking disc from the fixed object,
or removes the fixed base from the fixed object.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Please refer to FIG. 3 for the fixed base assembly of the mobile
phone according to the present invention. In FIG. 3, the fixed base
comprises a base 30, a sucking disc 40, and a clicking member 50;
wherein the base 30 is a cone symmetrical along the circumference;
a hollow cylinder 31 is extended upward from the center of the top
of the cone; a pair of corresponding rectangular through holes 32
is extended upward respectively from the cylinder 31 and an extended
position of the cone; a hollow is disposed at the bottom of the
cone (as shown in FIG. 4); the hollow and the cylinder 31 are interconnected;
one end of the cylinder 31 of the base 30 is coupled to a connecting
rod 33, and the other end of the connecting rod 33 has a clamping
base 34, and the clamping base 34 is used to clamp the mobile phone
(not shown in the figure).
Please refer to FIG. 3 again. The hollow at the bottom of the cone
can slide the base 30 onto the sucking disc 40, and the external
diameter of the sucking disc 40 is slightly greater than (or equal
to) the external diameter of the bottom of the base 30. A bar-shaped
pillar 41 is extended upward from the center of the sucking disc
40, such that the pillar 41 can be guided into the cylinder 31 more
stably and securely from the hollow at the bottom of the base 30,
and the base 30 can be slid and disposed successfully onto the sucking
disc 40 (as shown in FIG. 4), and a spring 42 is sheathed around
the periphery of the bar-shaped pillar 41 for a sliding movement
by expansions and contractions.
Please refer to FIG. 3 again. A through hole 51 is disposed at
the center of the rotary member 50, and has a size precisely sheathing
the rotary member 50 into the cylinder 31 and an extended position
of the cone. A symmetrical flange 511 is disposed on the periphery
of the through hole 51, and the height of the flange 511 is substantially
in the shape of waves and the connecting position of the symmetric
wave forms of the two flanges 511 forms a wave valley 512 and a
wave peak 513 at the center of the wave. In the meantime, a peg
60 is inserted into the pair of corresponding rectangular apertures
32 to pivotally couple the pillar 41 of the sucking disc 40, rotary
member 50, and base 30, and both ends of the peg 60 are exposed
from the flange 511.
From the aforementioned assembly of components, it is known that
when the fixed base is fixed onto a fixed object 70 (such as a cup
holder, or a car window, etc), the extended section 52 of the rotary
member 50 is rotated to lift both ends of the peg 60 along the wave-shaped
flange 511 to the wave peak 513 and compress the spring 42 accordingly,
so that the bottom of the base 30 presses against the sucking disc
40 to form a vacuum condition for attachment as shown in FIG. 4.
The sucking disc 40 will contract inward when the hollow at the
bottom of the base 30 is attached, and thus securely attach the
bottom of the base 30 onto a fixed object 70.
On the other hand, when the extended section 52 of the rotary member
50 is rotated, both ends of the peg 60 drop to the wave valley 512
from the wave-shaped flange 511. Since the compressed force is gone,
the resilience of the spring 42 will lift the bottom of the base
30 and separate the bottom of the base 30 from the sucking disc
40 as shown in FIG. 5 to successfully remove the fixed base.
Please refer to FIG. 3 again for a preferred embodiment of the
present invention. The external edge of the rotary member 50 is
a polygonal extended section 52. However such design is not limited
to the polygon shape in actual implementations. The shape of the
external edge of the rotary member 50 could be of any shape such
that the polygonal extended section 52 allows the user to rotate
the rotary member 50 easily.
Further, in this embodiment, the wave peak 513 of the flange 511
of the rotary member 50 has a fixed groove 514 such that after the
rotary member 50 is rotated, both ends of the peg 60 exposed from
the flange 511 fall into the fixed groove 514 to securely position
the peg 60, and allow users to have a definite feel about the section
of the peg.
Therefore, in summation of the description above, the most significant
feature of this invention resides on the simple design of the structures
of the base 30, sucking disc 40, and rotary member 50, not only
having the advantages of the easy-to-make mold, simple assembling,
and low manufacturing cost, but also having a very strong structure
of rotary member 50, which can prevent the cracking of the rotary
member 50 as the traditional clicking member 14 (as shown in FIG.
1) usually breaks after being exerted with a larger clicking force
and used for a long time. Thus, this invention can give the best
using condition in a long-time use, and the design of this invention
can effectively overcome the shortcomings of traditional device.
Therefore, this invention is regarded a humanistic design. |
