Please refer to FIG. 1, FIG. 1 shows a partial schematic diagram of a cover frame 11 of an electronic device that the liquid-blocking structure, according to an embodiment of the present invention, is applied to.
The electronic device herein set forth is, for example, a laptop computer, and the cover frame 11 of which may be a keyboard frame correspondingly. That is, the cover frame 11 is commonly known as the “C cover” in the field of laptop computers. As shown in FIG. 1, one side of the cover frame 11 may have an array of speaker holes 11sh. FIG. 1 is merely a partial illustration, it should be understood that the other opposite side of the cover frame 11 may also have an array of speaker holes 11sh to form a symmetrical sound output arrangement. As mentioned above, the electronic device is, for example, a laptop computer, and the array of speaker holes 11sh is so-called speaker sound holes. In view of the prior art, the speaker sound holes of the laptop computer may be easily penetrated by liquid (such as water), causing damage to the electronic parts/components inside the device, a liquid-blocking structure that can improve this problem is described below.
Please refer to FIG. 2A to FIG. 2B, FIG. 2A shows an explosion diagram of the liquid-blocking structure 100 and the cover frame 11 according to an embodiment, and FIG. 2B shows a bracket body 110 of the liquid-blocking structure 100.
The liquid-blocking structure 100 is suitable for electronic devices to prevent liquid flowing in from the array of speaker holes 11sh from penetrating into an interior of the electronic device and causing damage. As shown in FIG. 2A, the liquid-blocking structure 100 may include a bracket body 110 and a pad component 120. The bracket body 110 is arranged corresponding to the array of speaker holes 11sh. FIG. 2A shows a view from the back of the cover frame 11 in FIG. 1, namely the liquid-blocking structure 100 is disposed below the array of speaker holes 11sh, and the bracket body 110, the pad component 120 and the cover frame 11 of the electronic device are stacked vertically. The bracket body 110 can encompass the range of the array of speaker holes 11sh to ensure that liquid which may flow in from any local position of the array of speaker holes 11sh can be blocked. The pad component 120 is disposed between the cover frame 11 and the bracket body 110. The pad component 120 is, for example, non-woven fabric, which may be made of Mylar. The pad component 120 is laid under the array of speaker holes 11sh to mask the liquid-blocking structure 100, making the liquid-blocking structure 100 invisible in the appearance of the electronic device and providing an aesthetic effect.
As shown in FIG. 2B, the bracket body 110 may include a guide channel 111 and a liquid collection tank 112. The guide channel 111 and the liquid collection tank 112 both correspond to the bottom of the array of speaker holes 11sh. When liquid flows in from the array of speaker holes 11sh, the guide channel 111 receives the liquid and guides the liquid to flow into the liquid collection tank 112. The guide channel 111 may be designed to be slightly inclined to a horizontal plane, so as to accelerate the flow of liquid to the liquid collection tank 112. The liquid collection tank 112 may be provided with a drainage tube LT. When the liquid accumulates in the liquid collection tank 112 to a critical height, the drainage tube LT can drain a part of the liquid out of the liquid collection tank 112 from an outlet 112ex through its opening LT-h. That is, the drainage tube LT may be openly connected to an outside of the electronic device.
As shown in FIG. 2B, in the extension direction of the bracket body 110, a length L111 of the guide channel 111 is greater than a length L112 of the liquid collection tank 112. The liquid collection tank 112 may have an inclined surface b, and the inclined surface b is located at the connection between the liquid collection tank 112 and the guide channel 111. When the liquid is guided to the liquid collection tank 112 through the guide channel 111, the inclined surface b can help the liquid flow into the liquid collection tank 112 and prevent the liquid from flowing back to the guide channel 111. In the embodiment shown in FIG. 2A and FIG. 2B, the bracket body 110 of the liquid-blocking structure 100 and the cover frame 11 of the electronic device have corresponding fixing holes sh, so that the bracket body 110 can be fixed to the cover by locking. Specifically, the bracket body 110 and the cover frame 11 can be fixed, for example, by locking a screw to the fixing holes sh of the bracket body 110 and the cover frame 11 together. Corresponding to the fixation of the bracket body 110 and the cover frame 11, the pad component 120 is clamped between the bracket body 110 and the cover frame 11.
In the embodiment shown in FIG. 2A and FIG. 2B, since the bracket body 110 and the cover frame 11 have been locked and fixed on both sides, the middle portion of the bracket body 110 does not need to be locked and fixed to a base (not shown) of the electronic device. Said base of the electronic device is a component assembled with the cover frame 11. That is, the base is commonly known as the “D cover” in the field of laptop computers. If the middle portion of the bracket body 110 is further locked and fixed to the base of the electronic device, the middle portion of the bracket body 110 will be pulled up and down by the cover frame 11 and the base. This may easily cause liquid to leak from the guide channel 111 or even cause the bracket body 110 to deformation, thereby affecting the liquid-blocking performance.
Please refer to FIG. 3A and FIG. 3B. FIG. 3A shows an explosion diagram of the liquid-blocking structure 200 and the cover frame 11 according to another embodiment, and FIG. 3B shows a schematic diagram of the bracket body 210 of the liquid-blocking structure 200 in FIG. 3A.
The liquid-blocking structure 200 is suitable for electronic devices to prevent liquid flowing in from the array of speaker holes 11sh from penetrating into an interior of the electronic device and causing damage. As shown in FIG. 3A, the liquid-blocking structure 200 may include a bracket body 210 and a pad component 220. The bracket body 210 is arranged corresponding to the array of speaker holes 11sh. FIG. 3A shows a view from the back of the cover frame 11 in FIG. 1. That is, the liquid-blocking structure 200 is disposed below the array of speaker holes 11sh, and the bracket body 210, the pad component 220 and the cover frame 11 of the electronic device are stacked vertically. The bracket body 210 can encompass the range of the array of speaker holes 11sh to ensure that liquid which may flow in from any local position of the array of speaker holes 11sh can be blocked. The pad component 220 is disposed between the cover frame 11 and the bracket body 210. The pad component 220 is, for example, non-woven fabric, which may be made of Mylar. The pad component 220 is laid under the array of speaker holes 11sh to mask the liquid-blocking structure 200, making the liquid-blocking structure 200 invisible in the appearance of the electronic device and providing an aesthetic effect.
As shown in FIG. 3B, the bracket body 210 may include a guide channel 211 and a liquid collection tank 212. The guide channel 211 and the liquid collection tank 212 both correspond to the bottom of the array of speaker holes 11sh. When liquid flows in from the array of speaker holes 11sh, the guide channel 211 receives the liquid and guides the liquid to flow into the liquid collection tank 212. The guide channel 211 may be designed to be slightly inclined to a horizontal plane, so as to accelerate the flow of liquid to the liquid collection tank 212. The liquid collection tank 212 may be provided with a drainage tube LT. When the liquid accumulates in the liquid collection tank 112 to a critical height, the drainage tube LT can drain a part of the liquid out of the liquid collection tank 212 from an outlet 212ex through its opening LT-h. That is, the drainage tube LT may be openly connected to an outside of the electronic device.
As shown in FIG. 3B, in the extension direction of the bracket body 210, a length L211 of the guide channel 211 is greater than a length L212 of the liquid collection tank 212. The liquid collection tank 212 may have an inclined surface b, and the inclined surface b is located at the connection between the liquid collection tank 212 and the guide channel 211. When the liquid is guided to the liquid collection tank 212 through the guide channel 211, the inclined surface b can help the liquid flow into the liquid collection tank 212 and prevent the liquid from flowing back to the guide channel 211. In the embodiment shown in FIG. 3A and FIG. 3B, the bracket body 210 may have an annular area 210sr, and the guide channel 211 and the pad component 220 may be located within a range surrounded by the annular area 210sr. In the embodiment shown in FIG. 3A and FIG. 3B, the bracket body 210 of the liquid-blocking structure 200 can be fixed to the cover frame 11 by disposing an adhesive in the annular region 210sr. Specifically, the liquid-blocking structure 200 can be coated or attached with a frame glue on the annular area 210sr to be fixed to the cover frame 11, and the pad component 220 can be clamped between the bracket body 210 and the cover frame 11. Due to the inward arrangement of the annular area 210sr, it can be understood that the size of the pad component 220 is less than the pad component 120 of the previous embodiment.
In the embodiment shown in FIG. 3A and FIG. 3B, since the bracket body 210 is adhesively fixed to the cover frame 11 through the adhesive in the annular area 210sr, the middle portion of the bracket body 210 can be fixed to the base (not shown, commonly known as the “D cover” in the field of laptop computers) of the electronic device. Thus, it is not going to happen that the middle portion of the bracket body 210 is pulled up and down by the cover frame 11 and base and then liquid leaks from the guide channel 211 or even the bracket body 210 is deformed.
Please refer to FIG. 4, FIG. 4 shows a cross-sectional view of the drainage tube LT included in the bracket bodies 110 and 210 in FIG. 2B and FIG. 3B.
As shown in FIG. 4, the drain pipe LT includes a first tube portion T1 and a second tube portion T2. In the cross-section view, the first tube portion T1 and the second tube portion T2 present an inverted U-shaped structure, and the extension length LT1 of the first tube portion T1 is less than the extension length LT2 of the second tube portion T2. When the liquid flows into the liquid collection tank 112 (or the liquid collection tank 212), because the opening LT-h of the drainage tube LT fluidly connects the first tube portion T1 and the liquid collection tank 112 (or the liquid collection tank 212), a part of the liquid can flow into the first tube portion T1 through the opening LT-h and can be accommodated in the first tube portion T1 at a liquid level. At this time, based on the principle of Communicating Vessels, the liquid level of the liquid in the first tube portion T1 will be the same as that in the liquid collection tank 112 (or liquid collection tank 212). As the liquid accumulated in the liquid collection tank 112 (or the liquid collection tank 212) gradually increases, the liquid level in the first tube portion T1 also gradually increases. When the liquid level in the first tube portion T1 is higher than the critical height H, this part of the liquid will enter the second tube portion T2, then flow through the second tube portion T2 and be discharged out of the liquid collection tank 112 (or the liquid collection tank 212) from the outlet 112ex (or the outlet 212ex).
Based on the above, the present invention relates to a liquid-blocking structure for an electronic device, wherein the bracket body is provided with a guide channel and a liquid collection tank. The guide channel receives a liquid flowing into an array of speaker holes of the electronic device and guides the liquid to the liquid collection tank, thereby preventing the liquid from penetrating through the array of speaker holes into an interior of the electronic device. Further, the collected liquid can be discharged from the liquid collection tank through the arrangement of the drainage tube of the liquid collection tank. As such, internal electronic components of the electronic device can be protected from damage.
It will be apparent to those skilled in the art that various modifications and variations may be made to the disclosed embodiments. It is intended that the specification and examples be considered as exemplars only, with a true scope of the disclosure being indicated by the following claims and their equivalents.
