[0011] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.
[0012] Figure 1 is a schematic diagram of an electronic device according to an embodiment of the present invention. Figure 1 In this embodiment, the electronic device 10 may be a notebook computer, and includes a body 100, a display 200, and a keyboard set 300. Specifically, the display 200 is pivotally connected to the body 100, and the keyboard set 300 is disposed on the body 100.
[0013] Figure 2A yes Figure 1 A schematic partial cross-sectional view of the electronic device along line segment LL. Figure 2B yes Figure 2A A partial cross-sectional view from another perspective. Please refer to Figure 1 , Figure 2A and Figure 2B The machine body 100 has an internal space 101, an opening 102, a drainage hole 103 and a water collecting tank 104, wherein the opening 102 is a top opening and is used for installing the keyboard set 300. In other words, the keyboard set 300 is disposed in the opening 102. On the other hand, the drainage hole 103 is a bottom drainage hole relative to the opening 102, wherein the water collecting tank 104 is located in the internal space 101, and the drainage hole 103 is located in the water collecting tank 104.
[0014] Furthermore, the opening 102 and the drainage hole 103 are respectively located on opposite sides of the internal space 101, and the water collection tank 104 and the drainage hole 103 located in the water collection tank 104 are both within the projection range of the opening 102. Therefore, when liquid from the outside accidentally flows into the internal space 101 through the opening 102 or the gap in the keyboard assembly 300, the liquid can be drained to the water collection tank 104 and discharged to the outside through the drainage hole 103 to prevent the liquid from flowing to the battery, circuit board, CPU, GPU and other electronic components in the internal space 101. In other words, the drainage and drainage design consisting of at least the water collection tank 104 and the drainage hole 103 can not only drain the liquid to the outside, but also prevent the liquid from flowing to the battery, circuit board, CPU, GPU and other electronic components in the internal space 101 to avoid the battery, circuit board, CPU, GPU and other electronic components from malfunctioning or being damaged due to moisture.
[0015] like Figure 2A and Figure 2B As shown, in this embodiment, the electronic device 10 further includes a flow guiding structure 400. In detail, the flow guiding structure 400 includes a flow guiding cover 410 and a check valve 420, wherein the flow guiding cover 410 is disposed in the water collecting tank 104, and the check valve 420 is integrated with the flow guiding cover 410. The flow guiding cover 410 is used to close the opening of the water collecting tank 104, and has a pipe 411 connected to the water collecting tank 104. Therefore, the liquid can be drained to the water collecting tank 104 via the pipe 411. In other words, the flow guiding cover 410 also serves as a part of the drainage design.
[0016] The pipe 411 of the guide cover 410 is located between the opening 102 and the drain hole 103, and the keyboard set 300 is located above the guide cover 410 and the water collection tank 104. Further, the keyboard set 300 includes a bottom plate 310 disposed in the internal space 101 and a keyboard body 320 disposed on the bottom plate 310, and the bottom plate 310 is located between the guide cover 410 and the keyboard body 320. When external liquid flows into the internal space 101, the bottom plate 310 can receive the liquid to prevent the liquid from flowing to the battery, circuit board, central processing unit, graphics processing unit and other electronic components in the internal space 101. In other words, the bottom plate 310 is also used as a part of the drainage design.
[0017] like Figure 2A and Figure 2B As shown, in this embodiment, the bottom plate 310 has a drainage hole 311, and the drainage hole 311 is located opposite to the pipe 411. When liquid flows into the internal space 101 and is received by the bottom plate 310, the liquid can flow to the drainage hole 311 on the bottom plate 310, and then flow into the water collection tank 104 through the drainage hole 311 and the pipe 411 in sequence, and finally discharged to the outside from the drainage hole 103.
[0018] On the other hand, the bottom plate 310 also has a recess 312 that abuts against the flow guide cover 410, and the drainage hole 311 is located in the recess 312. When liquid flows into the internal space 101 and is received by the bottom plate 310, the liquid can be collected in the recess 312, and then flow into the water collection tank 104 through the drainage hole 311 and the pipe 411 in sequence. For example, the recess 312 of the bottom plate 310 and the flow guide cover 410 fit tightly to prevent the liquid flowing through the drainage hole 311 from leaking into the internal space 101 through the gap between the recess 312 and the flow guide cover 410.
[0019] like Figure 2A and Figure 2BAs shown, in this embodiment, the guide cover 410 includes a top cover 410a and a side wall 410b connected to the top cover 410a, wherein the pipe 411 passes through the top cover 410a, and the recess 312 of the bottom plate 310 and the top cover 410a are tightly fitted. In addition, the side wall 410b surrounds the top cover 410a to define a groove 410c facing the drain hole 103. Specifically, the side wall 410b is inserted into the water collecting tank 104 and protrudes toward the bottom surface 104a of the water collecting tank 104. In addition, the groove 410c is connected to the water collecting tank 104.
[0020] The side wall 410b is in contact with the inner wall surface 104b of the water collecting tank 104 and is closely fitted to the inner wall surface 104b to prevent the liquid flowing into the groove 410c and the water collecting tank 104 from leaking into the internal space 101 through the gap between the side wall 410b and the inner wall surface 104b. On the other hand, the electronic device 100 further includes a sealing member 500, wherein the sealing member 500 can be a waterproof ring and is disposed on the bottom surface 104a.
[0021] Further, the seal 500 is arranged around the bottom surface 104a, the side wall 410b and the inner wall surface 104b, and is pressed between the bottom surface 104a and the inner wall surface 104b by the side wall 410b. Further, the seal 500 is tightly attached to the side wall 410b, the bottom surface 104a and the inner wall surface 104b to prevent the liquid flowing into the groove 410c and the sump 104 from leaking into the internal space 101 through the gap between the side wall 410b and the bottom surface 104a and the gap between the side wall 410b and the inner wall surface 104b.
[0022] like Figure 2A and Figure 2B As shown, in this embodiment, the guide cover 410 also includes a column 410d protruding from the top cover 410a to the bottom surface 104a of the water collection tank 104, wherein the pipe 411 passes through the top cover 410a and the column 410d, and the end of the column 410d does not contact the bottom surface 104a of the water collection tank 104, or in other words, there is a gap between the end of the column 410d and the bottom surface 104a of the water collection tank 104.
[0023] In detail, the pipe 411 has a first opening 411a located at the top cover 410a and a second opening 411b located at the end of the column 410d, wherein the check valve 420 is integrated in the pipe 411 and disposed between the first opening 411a and the second opening 411b. The check valve 420 is suitable for controlling the flow direction of the liquid, especially preventing the liquid flowing into the groove 410c and the sump 104 from flowing back to the internal space 101 through the pipe 411.
[0024] Figure 3A yes Figure 2A A partial cross-sectional schematic diagram of an electronic device flipped to another state. Figure 3B yes Figure 3A A schematic diagram of a partial section from another viewing angle. Figure 2A and Figure 2B The electronic device 10 is shown in the first placement state, with the keyboard set 300 facing upward. Figure 3A and Figure 3B The electronic device 10 is shown in the second placement state, with the keyboard set 300 facing downward.
[0025] Please refer to Figure 2A and Figure 3A or reference Figure 2B and Figure 3B The check valve 420 may be a gravity check valve and includes a ball 421 disposed in the pipe 411 and adapted to slide between the first opening 411a and the second opening 411b. In other words, the check valve design at least comprises the guide cover 410 and the check valve 420.
[0026] In the first placement state, the ball 421 moves to the second opening 411b due to the gravity G. Since the ball 421 does not block the second opening 411b, the path for the liquid to flow through the pipe 411 to the sump 104 or the groove 410c remains unobstructed, ensuring that the liquid is drained to the drain hole 103 and further discharged to the outside.
[0027] When the electronic device 10 is turned over to the second placement state, the ball 421 moves to the first opening 411a due to the gravity G. Since the ball 421 blocks the first opening 411a, the path for the liquid to flow back from the water collection tank 104 or the groove 410c to the internal space 101 through the pipe 411 is blocked. In other words, during the turning process of the electronic device 10, the liquid cannot flow back from the water collection tank 104 or the groove 410c to the internal space 101 through the pipe 411, thereby preventing the battery, circuit board, CPU, GPU and other electronic components from malfunctioning or being damaged due to moisture.
[0028] On the other hand, when the electronic device 10 is turned over to the second placement state, the liquid remaining in the water collection tank 104 or the groove 410c without being discharged to the outside through the drainage hole 103 can fall into the top cover 410a in the groove 410c. Because the column 410d protrudes from the top cover 410a to the bottom surface 104a of the water collection tank 104, under the obstruction of the column 410d, or under the limitation of the height difference between the top cover 410a and the second opening 411b, the remaining liquid cannot flow into the pipeline 411 through the second opening 411b, which greatly reduces the possibility of the liquid flowing back to the internal space 101.
[0029] Please refer to Figure 2A and Figure 3A or reference Figure 2B and Figure 3BIn this embodiment, the outer diameter of the ball 421 is larger than the aperture of the first opening 411a and smaller than the aperture of the second opening 411b. Therefore, when the ball 421 is moved to the first opening 411a by the gravity G, the ball 421 can block the first opening 411a. On the other hand, the end of the column 410d has a plurality of positioning protrusions 410e protruding in the second opening 411b, which are used to stop the ball 421 moving toward the second opening 411b and prevent the ball 421 from escaping from the pipe 411 from the second opening 411b. When the ball 421 is moved to the second opening 411b by the gravity G, the ball 421 contacts the plurality of positioning protrusions 410e and stops moving. Furthermore, because the outer diameter of the ball 421 is smaller than the aperture of the second opening 411b, the second opening 411b is not blocked by the ball 421 and remains unobstructed.
[0030] In addition, the diameter of the pipe 411 between the first opening 411a and the second opening 411b is larger than the outer diameter of the sphere 421 and can be equal to the aperture of the second opening 411b to facilitate the movement of the sphere 421 in the pipe 411 and maintain the fluidity of the liquid in the pipe 411.
[0031] In summary, when liquid from the outside flows into the internal space, the liquid can be drained to the water collection tank through the pipe and discharged to the outside through the drain hole. In addition, the check valve can prevent the liquid drained to the water collection tank from flowing back to the internal space through the pipe. In other words, the waterproof design of the electronic device of the present invention includes a drainage design and a check design, which can not only drain the liquid to the outside, but also prevent the liquid from flowing to the battery, circuit board, central processing unit, graphics processor and other electronic components in the internal space, so as to avoid the battery, circuit board, central processing unit, graphics processor and other electronic components from malfunctioning or being damaged due to moisture, so it has excellent waterproof performance.
