Mobile Phone Patent Description
BACKGROUND
1. Field of Invention
The present invention relates to a mobile phone positioning apparatus.
More particularly, the present invention relates to a mobile phone
positioning apparatus for radiation testing.
2. Description of Related Art
Mobile phones have become an important communication device accompanying
everyone. Because the human body is exposed to high levels of electromagnetic
radiation generated by the mobile phone, each type of mobile phone
needs to comply with limits for safe cell phone radiation exposure.
The radiation test for a mobile phone is generally executed in
a chamber during the development or certification period to verify
whether the mobile phone meets limits for safe cell phone radiation
exposure or not. In radiation test procedures, a mobile phone is
essentially positioned along three different planes (H, E.sub.1
and E.sub.2). The conventional positioning apparatus for radiation
testing has to switch among the three planes manually. Opening a
gate of the radiation test chamber and adjusting the H, E.sub.1
or E.sub.2 plane manually is inconvenient and time-consuming.
SUMMARY
It is therefore an objective of the present invention to provide
a mobile phone positioning apparatus for radiation testing.
In accordance with the foregoing and other objectives of the present
invention, a mobile phone positioning apparatus provides a rotational
movement and a switching function to adjust the three planes as
requested by a radiation test. The positioning apparatus includes
a base, a support shaft, a platform and a testing plane switch apparatus.
The testing plane switch apparatus is mounted on the platform. An
inverse U frame is fixed on the platform. A testing frame, pivotally
connected to the inverse U frame, is rotated by two pneumatic cylinders
so as to switch between the H plane and either the E.sub.1 or E.sub.2
plane by 90 degrees. A testing plate, pivotally connected with the
testing frame, is rotated by another pneumatic cylinder so as to
switch between the E.sub.1 and E.sub.2 planes by 90 degrees.
Thus, the mobile phone positioning apparatus can be easily controlled
by a computer to automatically switch between the three planes.
Time and labor consumed in radiation testing can be decreased. Moreover,
pneumatic cylinders made of low reflection coefficient materials
are applied so as not to influence RF signals in a test chamber.
It is to be understood that both the foregoing general description
and the following detailed description are by examples and are intended
to provide further explanation of the invention as claimed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to the present preferred embodiments
of the invention, examples of which are illustrated in the accompanying
drawings. Wherever possible, the same reference numbers are used
in the drawings and the description to refer to the same or like
parts.
In order to save labor and time consumed by radiation testing,
the present invention provides a labor-saving mobile phone positioning
apparatus to switch among three planes (H, E.sub.1 and E.sub.2).
Moreover, a cylinder made of low reflection coefficient materials
is applied to this positioning apparatus so as not to influence
RF signals.
FIG. 1 illustrates a perspective view of a mobile phone positioning
apparatus for radiation testing according to one preferred embodiment
of this invention. The major function of this mobile phone positioning
apparatus is to provide rotational movement and switching of the
three planes (H, E.sub.1 and E.sub.2) for radiation testing. The
mobile phone positioning apparatus includes a base 100, a support
shaft 101, a platform 105 and a testing plane switch apparatus 140.
The base 100 contains a motor 146 inside. The support shaft 101
is mounted on a rotary shaft 148 of the motor 146, thus enabling
the motor 146 to drive the support shaft 101 so as to provide the
rotational movement for the radiation test. The support shaft 101,
which is hollow, holds another support shaft 104 by a knob 148.
The support shaft 104 can be manually adjusted (when the knob 148
is released) to provide the platform 105 a desired height. The testing
plane switch apparatus 140 is mounted on the platform 105. Fundamental
parts of the testing plane switch apparatus 140 are an inverse U-shaped
frame 142, a testing frame 144 and a testing plate 116. The inverse
U-shaped frame 142 is fixed on the platform 105. The testing frame
144 is pivotally connected to the inverse U-shaped frame 142 by
a joint 112. Two pneumatic cylinders 108 and 110, which are attached
to two sides of the inverse U-shaped frame 142, drive the testing
frame 144 (by pushing rods 107 and 115) to perform a 90-degree rotation
movement back and forth. The testing plate 116 is pivotally connected
to a top end of the testing frame 144 by a joint 114. A pneumatic
cylinder 106, which is mounted on the platform 105, can drive the
testing plate 116 to perform a rotational movement. In radiation
testing procedures, the testing plate 116 is used to secure a mobile
phone. Other driving devices, such as an apparatus containing a
motor, can replace the pneumatic cylinders. The mobile phone positioning
apparatus (including the pneumatic cylinders) for radiation testing
is preferably made of low reflection coefficient materials, such
as transparent plastic or acrylic materials, so as not to influence
RF signals in the test chamber. Due to the application of the pneumatic
cylinder, a computer can be easily used to automatically control
a radiation test for a mobile phone.
FIG. 2A illustrates a top view of a mobile phone positioning apparatus
for radiation testing according to one preferred embodiment of this
invention. FIG. 2A demonstrates how the pneumatic cylinder 106 drives
the testing plate 116. The testing plate 116 has a rotation rod
120 perpendicular to itself. The pneumatic cylinder 106 has a pushing
rod 118, which drives the rotation rod 120 or the testing plate
116 to move the testing plate 116 counter-clockwise. When the mobile
phone positioning apparatus switches between the E.sub.1 and E.sub.2
planes, the testing plate 116 needs to be rotated counter-clockwise
by 90 degrees.
FIGS. 2B and 2C respectively illustrate side views of two different
operation states of a testing plane switch apparatus according to
one preferred embodiment of this invention. FIG. 2B illustrates
a side view of FIG. 2A. When the pneumatic cylinder 106 (referring
to FIG. 2A) drives the testing plate 116 to move counter-clockwise,
the testing plate 116 needs to stay as illustrated in FIG. 2B. When
the testing plane switch apparatus 140 desires to demonstrate the
E.sub.1 or E.sub.2 plane, i.e., switching from the H plane to either
the E.sub.1 or E.sub.2 plane, the testing frame 144 needs to rotate
90 degrees as illustrated in FIG. 2C. When the testing plane switch
apparatus 140 desires to switch from the E.sub.1 plane to the E.sub.2
plane (or from the E.sub.2 plane to the E.sub.1 plane), the testing
frame 144 needs to return to the state illustrated in FIG. 2B so
as to rotate the testing plate 116 counter-clockwise (from the E.sub.1
plane to the E.sub.2 plane or from the E.sub.2 plane to the E.sub.1
plane); and then the testing frame 144 rotates 90 degrees again
as illustrated in FIG. 2C to complete a switch cycle between the
E.sub.1 plane and the E.sub.2 plane.
FIG. 3 illustrates a perspective view of the H plane demonstrated
by the testing plane switch apparatus according to one preferred
embodiment of this invention. When the radiation test is performed,
a double-sided adhesive tape 122 (or an adhesive material layer)
is used to secure a mobile phone 130 to the testing plate 116; and
the mobile phone 130 driven (rotated) by the motor 146 (remaining
at the H plane) moves.
FIG. 4 illustrates a perspective view of the E.sub.1 plane demonstrated
by the testing plane switch apparatus according to one preferred
embodiment of this invention. The testing plate 116 illustrated
in FIG. 3 (the H plane) driven (rotated) by the pneumatic cylinder
106 rotates 90 degrees and the testing frame 144 driven (rotated)
by the pneumatic cylinders 108 and 110 rotates 90 degrees so that
the testing plate 116 switches from the H plane (illustrated in
FIG. 3) to the E.sub.1 plane (illustrated in FIG. 4).
FIG. 5 illustrates a perspective view of the E.sub.2 plane demonstrated
by the testing plane switch apparatus according to one preferred
embodiment of this invention. The testing plate 116 illustrated
in FIG. 3 (the H plane) driven (rotated) by the pneumatic cylinders
108 and 110 rotates 90 degrees so that the testing plate 116 switches
from the H plane (illustrated in FIG. 3) to the E.sub.2 plane (illustrated
in FIG. 5).
According to the preferred embodiments of the present invention,
the mobile phone positioning apparatus can be easily controlled
by a computer to automatically switch three planes (H, E.sub.1 and
E.sub.2). Time and labor consumed in radiation testing can be decreased.
Moreover, pneumatic cylinders made of low reflection coefficient
materials are applied so as not to influence RF signals in a test
chamber.
It will be apparent to those skilled in the art that various modifications
and variations can be made to the structure of the present invention
without departing from the scope or spirit of the invention. In
view of the foregoing, it is intended that the present invention
cover modifications and variations of this invention provided they
fall within the scope of the following claims and their equivalents.
