Mobile Phone Patent Description
This application incorporates by reference Taiwanese application
Ser. No. 90202276, Filed Feb. 15, 2001.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates in general to a mobile phone display unit,
and more particularly to a slidably detachable mobile phone display
unit.
2. Description of the Related Art
Along with the busy communication between people, the mobile phone
has become an indispensable communication tool for modern people.
Through it, people can conveniently communicate with each other
no matter wherever they are or whenever they want to. In the pursuit
of fashion, the users desire that their mobile phones are conspicuous
and different from that of others'. Mobile phone outer coverings
of varied patterns have been designed to satisfy users' needs and
preferences.
Please referring to FIG. 1, a block diagram of a conventional folding-type
mobile phone is illustrated. In FIG. 1, the mobile phone 100 includes
an operation base 102 and a display unit 104. The display unit 104,
being connected to the operation base 102 through a joint device
(not shown in the diagram), can be closed to the base unit 102 or
be opened from it. The user inputs signals via the keypad 106 of
the base unit 102. The display unit 104 further includes an upper
covering member 108, a lower covering member 110 and a Liquid Crystal
Display (LCD) 112, which is used to display the status and information
of the mobile phone 100. Of which, the click-and-hook joint mechanism
is a commonly used joint mechanism which tightly joints the upper
covering member 108 and the lower covering member 110 together.
The two covering members 108 and 110 are therefore tightly fastened
together with joint marks 114 lying between them, forming the outer
covering 109 with the LCD 112 enclosed inside it. In addition, there
is a window 108 lying in the upper covering member 108, which covers
the LCD 112.
In circumstances when the users want to replace the outer covering,
or when parts of the circuits of the display unit 104 are damaged
or the LCD 112 is out of order, normally the users need to take
apart the upper and lower covering members 108 and 110 first before
they can replace the outer covering or fix up the damaged circuits
of the display unit 104. In order to replace the outer covering
109, i.e., the upper covering member 108 and the lower covering
member 110 of the display unit 104, the users always need to take
apart the mechanic parts of the click-and-hook joint mechanism using
a screwdriver. In case the outer covering 109 is damaged after being
taken apart, a new one is required to enclose the internal parts
of the display unit 109 wasting both time and money. Besides, the
LCD 112, which is enclosed within the outer covering 109, is just
sandwiched between the upper covering member 108 and the lower covering
member 110. Since the upper covering member 108 and the lower covering
member 110 are normally made of fragile solid materials which can
hardly support and protect the LCD 112 from hits of external sources.
In terms of outlooks, the joint marks 114, which lie between the
upper covering member 108 and the lower covering member 110, spoil
the integral beauty of the mobile phone 100.
SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide a slidably
detachable mobile phone display unit with its outer covering and
frame being designed in such a way that the outer covering can be
detached from the frame directly and the replacement of the outer
covering can be done thereby. As for the frame, its hard and strong
structure protects and supports the LCD; and its features of being
small, thin and light facilitate the convenience of portability
for the users. The seamless outer covering without any joint marks
features the integral beauty of the mobile phone.
A slidably detachable mobile phone display unit including a frame
and an outer covering is provided according to the object of the
invention. The frame has a chamber into which a display panel is
fixed. The outer covering and the frame are jointed together in
a slidably detachable way.
In addition, a slidably detachable mobile phone display unit including
a frame, an outer covering and screws is provided. The frame has
tooling holes and a chamber into which a display panel is fixed.

the frame in a slidably detachable way and exposes the display panel
through the openings. Besides, the screws, passing through the screw
holes, are screwed into the tooling holes to fix the frame and the
outer covering together.
BRIEF DESCRIPTION OF THE DRAWINGS
Other objects, features, and advantages of the invention will become
apparent from the following detailed description of the preferred
but non-limiting embodiments.
The description is made with reference to the accompanying drawings
in which:
FIG. 1 is a schematic diagram of a conventional folding-type mobile
phone; and
FIG. 2 is an exploded diagram of a slidably detachable mobile phone
display unit according to a preferred embodiment of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Regarding the design of the display unit of a folding-type mobile
phone, the invention assembles the mobile phone display unit using
a frame and an outer covering.
The outer covering can either be jointed to the frame using a slidably
detachable design or a fixed one. Protecting and supporting the
display panel by means of a frame, whose hard and strong structure
is light and thin, the size and manufacturing cost of the display
unit can be reduced. The joint marks can even be avoided featuring
the integral beauty of the mobile phone.
Referring to FIG. 2, an exploded diagram of a slidably detachable
mobile phone display unit is illustrated. The display unit 200 as
shown in FIG. 2 includes a frame 202 and an outer covering 204.
The outer covering 204 can be directly jointed to the frame 202
in a slidably detachable way. The frame 202 has a chamber 206 and
a number of tooling holes 208. The number of the tooling hole 208,
for instance, can be two. The chamber 206 can be used to accommodate
a display panel such as an LCD. The frame 202 according to the design
of the invention protects and supports LCD. The outer covering 204
includes an upper joint casing 210 and a lower joint casing 212.
Of which, the upper joint casing 210 has a number of screw holes
214 corresponding to the tooling holes 208, an extension section
214 and an upper opening 218. The number of the screw holes 214
is two for instance. Besides, the lower joint casing 212 has a junction
section 220 and a lower opening 222. Whereas the junction section
220 can joint with the extension section 216; the upper opening
218 and the lower opening 222 form an opening (not shown here) allowing
the LCD to be exposed from the outer covering 204.
The frame 202 can be encased in the outer covering 204 by following
the following procedures. Firstly, match the guiding slot 230 of
the lower joint casing 212 with the sliding channel 240 of the frame
202 and then slip the guiding slot 230 alongside the sliding channel
240 according to the direction of the arrow sign shown in FIG. 2.
Next, let the extension section 216 of the upper joint casing 210
be fastened to the junction section 220 of the lower joint casing
212 according to the direction of the arrow sign as well. Finally,
the screws 224, passing through the screw holes 214 on the upper
joint casing 210, are screwed into the tooling holes 208 on the
frame 202 fastening the outer covering 204 and the frame 202 firmly.
However, the outer covering 204 can be detached from the frame 202
by simply reversing the above procedures.
As a consequence, if the users desire to detach the outer covering
204 from the frame 202 and replace it with a stylish one, they only
need to follow the above procedures accordingly. It is noteworthy
that the outer covering 204 can be formed in a unity of the upper
joint casing 210 and the lower joint casing 212 without losing its
original function for being able to be slidably detachable from
the frame 202 and replaced accordingly. The outer covering 204 with
varied designs of outlook is made of plastic materials. Since the
structure of the frame 202 must be hard and strong enough to protect
and support the LCD, the frame 202 can be made of engineering plastics
or formed through the die-casting process using aluminum or magnesium.
The outer covering 204 and the frame 202 are designed such that
the outer covering 204 can be slidably detached from and replaced
on the frame 202 directly; whereas the frame, which is hard and
strong, protects and supports the LCD. Furthermore, because of the
small-sized, thin and light features of the frame 202, it provides
the users more convenience when carrying the mobile phones. The
seamless outlook of the outer covering features the integral beauty
of the mobile phone.
The slidably detachable mobile phone display unit according to
the abovementioned preferred embodiments facilitates convenient
replacement of the outer coverings by a design allowing the outer
covering to be slidably detachable from the frame. The frame, being
hard and strong, support and protect the display panel from being
damaged by hits of external sources. In addition, the frame, being
small-sized, light and thin, makes it easier for the users to carry
the mobile phones with them. Moreover, the seamless outlook of the
outer covering without any joint marks features the integral beauty
of the mobile phone.
While the invention has been described by way of example and in
terms of the preferred embodiment, it is to be understood that the
invention is not limited to the disclosed embodiment. To the contrary,
it is intended to cover various modifications and similar arrangements
and procedures, and the scope of the appended claims therefore should
be accorded the broadest interpretation so as to encompass all such
modifications and similar arrangements and procedures.
