Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a waterproof structure,
especially to a waterproof structure for use in display device.
[0003] 2. Description of Related Art
[0004] With the development of technology, an electronic device
having a screen is commonly used in our daily lives for the purpose
of transmitting data at work, exchanging messages or even providing
entertainments. A general electronic device, such as a portable
device, a smart phone, a tablet computer or even an industrial
computer, has become a media widely used by consumers. Also, some
consumers heavily rely on these electronic devices, for example
thinking about various issues or taking a drink in front of a
computer, watching TV in a bathroom, bringing the electronic device
while going out, or even operating a computer in a severe
environment.
[0005] For these precision display devices, moisture may permeate
into the electronic device because of poor production or improper
operation by consumers. For ensuring the performance and the
service life of a display device, a waterproof structure is often
installed for reducing the possibility of moisture permeating into
the interior of a display device. A conventional waterproof
structure for use in display device is to install one or a
plurality of waterproof strips at the periphery of the display
device, so a waterproof objective can be achieved through the
waterproof strips being provided on a panel and a front frame.
However, the right-angle connecting locations defined between the
waterproof strips are unable to be tightly engaged, and a gap is
very easily to be formed at the right-angle connecting locations,
so a poor waterproof performance is caused and moisture is allowed
to easily permeate. In addition, after the waterproof strip being
used for a period of time, the waterproof strip would be
deteriorated and fatigued, so the tight adhesion is no longer
provided between the waterproof strip and the front frame or
between the waterproof strip and the panel, and a situation of
water or moisture permeating would occur which may cause short
circuit, malfunction or loose contact in the electronic device.
[0006] For improving the existed problems, some skilled people in
the art provide a design of installing waterproof structures (not
limited to the above-mentioned waterproof strip) at proper
locations of the display device; however, the installation of each
additional waterproof structure would result in more complicated in
production, increasing the production cost and hard to simplify the
production procedure for satisfying massive production.
[0007] In view of the above-mentioned problems, the applicant of
the present invention provides a design of enabling the water
permeated into the display device to be easily discharged while the
display device being in use, so the water can be prevented from
being remained inside the machinery and the smooth operation of
internal components can be ensured.
SUMMARY OF THE INVENTION
[0008] The present invention is to provide a waterproof structure
for use in display device capable of effectively buffering the
speed of moisture permeating into the display device so as to
prolong the service life.
[0009] The present invention is to provide a waterproof structure
for use in display device capable of effectively discharging water
thereby preventing the water from being remained in the display
device so as to ensure the smooth operation of internal
components.
[0010] Accordingly, the present invention provides a waterproof
structure for use in display device, which includes a back cover, a
display module and a waterproof member. The back cover includes a
peripheral part of back cover, a stop part connected to the
peripheral part of back cover, and a groove defined between the
peripheral part of back cover and the stop part, wherein the height
of the peripheral part of back cover is greater than the height of
the stop part. The display module is disposed on the back cover.
The waterproof member is disposed between the display module and
the stop part.
[0011] Preferably, the peripheral part of back cover and the stop
part are continuously connected thereby forming an enclosed
rectangular shape allowing the display module to be disposed. The
groove further includes a plurality of partition pieces, each of
the partition pieces is respectively connected to one lateral wall
of the peripheral part of back cover and one lateral wall of the
stop part, and the length/height of each of the partition pieces is
smaller than the length/height of the stop part. Each of the
partition pieces is formed in a rectangular, elliptical or
polygonal shape.
[0012] Preferably, the waterproof member is formed in an annular
status and adhered on one lateral surface of the display module.
The waterproof member is integrally formed as an annular structure
adhered on one lateral surface of the display module. The
waterproof member includes two waterproof parts, and the cutting
surface of each of the waterproof parts is respectively formed as
an inclined surface or a polygonal surface for being engaged with
each other so as to form an annular structure.
[0013] In comparison with related art, the present invention has
advantageous features as follows. Through each of the partition
pieces being connected to the peripheral part of back cover and the
stop part, the danger of water or moisture permeating into the
display module can be further relieved, so the display module is
able to be prevented from being damaged or abnormally operated, and
an advantage of convenient in production can also be provided. In
other words, the installation of the partition pieces can solve the
problem of the stop part generating stress concentration due to the
smaller dimension, and the groove between the peripheral part of
back cover and the stop part is also provided with an advantage of
allowing a mold to be easily released. Moreover, for increasing the
production efficiency and enhancing the positioning effect, the
present invention further includes a supporter. The supporter
installed corresponding to the back cover is formed with at least
one semi-circular positioning post allowing at least one
positioning hole formed on the back cover to be assembled and
positioned.

tablet computer, an industrial computer or other similar electronic
devices. However, according to other embodiments, the display
device can also be an electronic device having a screen, such as a
notebook computer, a mobile phone, a digital camera, a monitor or
other electronic devices. The backlight source of the display
device includes, but not limited to, a liquid crystal, light
emitting diode (LED) or plasma for providing the backlight source.
Preferred embodiments of the present invention will be described
with reference to the drawings.
[0025] Please refer from FIG. 1 to FIG. 3, the waterproof structure
for use in display device includes a back cover (100), a display
module (200) and a waterproof member (300). The back cover (100)
includes a peripheral part of back cover (110), a stop part (120)
connected to the peripheral part of back cover (110) and a groove
(130) defined between the peripheral part of back cover (110) and
the stop part (120), wherein the height of the peripheral part of
back cover (110) is greater than the height of the stop part (120).
The display module (200) is disposed on the back cover (100). The
waterproof member (300) is disposed between the display module
(200) and the stop part (120).
[0026] According to this embodiment, a supporter (500) is further
included for being assembled with the back cover (100). For
increasing the production efficiency and enhancing the positioning
effect, at least one semi-circular positioning post (550) is formed
on the supporter (500) corresponding to the back cover (100),
thereby allowing at least one positioning hole (150) formed on the
back cover (100) to be assembled and positioned. As shown in FIG.
1, the supporter (500) further includes an upper support (510) and
a lower support (520) and a connection piece (530) respectively
connected to the upper support (510) and the lower support (520).
Substantially, each of the semi-circular positioning posts (550) is
preferably to be respectively formed on one lateral surface of the
upper support (510) and one lateral surface of the lower support
(520), thereby allowing the corresponding positioning holes 150 of
the back cover (100) to be assembled and positioned. The
semi-circular positioning post (550) is provided with an advantage
of less likely to generate stress concentration thereby avoiding
the occurrence of deformation, and a more precise positioning
relation can be formed between the semi-circular positioning post
(550) and the positioning hole (150).
[0027] As shown in FIG. 2, the display module (200) includes a
display panel (210), a backlight source (220), a drive IC and
circuit board (230) or other components. The display module (200)
is deemed as a prior art, therefore no further illustration is
provided. As shown in FIG. 1 and FIG. 2, the peripheral part of
back cover (110) and the stop part (120) are continuously connected
thereby forming an enclosed rectangular shape allowing the display
module (200) to be disposed. As shown in FIG. 3, the groove (130)
further includes a plurality of partition pieces (140), and each of
the partition pieces (140) is respectively connected to one lateral
wall of the peripheral part of back cover (110) and one lateral
wall of the stop part (120); in other words two sides of each of
the partition pieces (140) are respectively connected to the
lateral wall of the peripheral part of back cover (110) and the
lateral wall of the stop part (120) defined in the groove (130),
the above-mentioned structure will be further disclosed
thereinafter.
[0028] For allowing the display module (200) to be easily assembled
with the back cover (100), the back cover (100) can be formed with
an assembly tolerance for facilitating the assembly of the display
module (200). As shown in FIG. 3, one side of the display module
(200) or the waterproof member (300) is adjacently connected to an
inner wall of the peripheral part of back cover (110), so water may
enter from the assembly tolerance. However, the groove (130)
between the peripheral part of back cover (110) and the stop part
(120) is able to provide a buffering effect, so water is prevented
from directly flowing in from a gap defined between the back cover
(100) and the display module (200). Even if the water accidentally
flows in the groove (130) disclosed in this embodiment, the groove
(130) can be served to effectively discharge the water, thereby
preventing water from remaining in the electronic device, and the
smooth operation of internal components can be ensured. Moreover,
according to the embodiment disclosed in FIG. 3, the
thickness/width of the peripheral part of back cover (110) is
greater than the thickness/width of the stop part (120).
[0029] Please refer to FIG. 4, the waterproof member (300) is
formed in an annular status and adhered on one lateral surface of
the display module (200). Preferably, the waterproof member (300)
is integrally formed as an annular structure (310) adhered on one
lateral surface of the display module (200). As shown in FIG. 4,
the waterproof member (300) can also be formed as the annular
structure (310) composed of two waterproof parts (320), (330) being
engaged with each other. For preventing moisture from permeating
into the display module (200) from the cutting edges of the
waterproof parts (320), (330), the cutting surface of each of the
waterproof parts (320), (330) is formed as an inclined surface as
shown in FIG. 5. According to the embodiment disclosed in FIG. 6,
the cutting surface of each of the waterproof parts (320), (330)
can also be formed as a polygonal surface or other suitable
geometric surface. Moreover, the material of which the waterproof
member (300) is made can be: silicon, plastic, rubber, Polyethylene
Terephthalate (PET) or other suitable materials.
[0030] Please refer to FIG. 7 and FIG. 8, each of the partition
pieces (140) arranged at the periphery of the back cover (100) is
mainly served to increase the difficulty for moisture entering the
display module (200); in other words the time for moisture directly
permeating into the electronic device can be buffered. According to
this embodiment, the length/height of each of the partition pieces
(140) is smaller than the length/height of the stop part (120).
However, according to the embodiment disclosed in FIG. 9 and FIG.
10, the length/height of each of the partition pieces (140) can
also be equal to the length/height of the stop part (120) with
respect to the actual needs. Moreover, the shape of each of the
partition pieces (104) can be for example but not limited to
rectangular, elliptical or polygonal.
[0031] Through each of the partition pieces (140) being connected
to the peripheral part of back cover (110) and the stop part (120),
the danger of water or moisture permeating into the display module
(200) can be further relieved, the display module (200) is able to
be prevented from being damaged or abnormally operated, and an
advantage of convenient in production can also be provided. In
other words, the installation of the partition pieces (140) can
solve the problem of the stop part (120) generating stress
concentration due to the smaller dimension, and the groove (130)
between the peripheral part of back cover (110) and the stop part
(120) is also provided with an advantage of allowing a mold to be
easily released.
[0032] Although the present invention has been described with
reference to the foregoing preferred embodiment, it will be
understood that the invention is not limited to the details
thereof. Various equivalent variations and modifications can still
occur to those skilled in this art in view of the teachings of the
present invention. Thus, all such variations and equivalent
modifications are also embraced within the scope of the invention
as defined in the appended claims.
