As can be seen from the above, the present invention has progressive patent requirements.

Please refer to FIG. 9-10, which is a schematic diagram of a second embodiment of the human-machine interface device of the present invention. As shown in FIG. 9, the human interface device 30 can include a panel 31, a back cover 32, and a display 33 and a circuit board (not shown). The panel 21 may further include a plurality of through holes 316, a plurality of water guiding grooves 317, a plurality of water guiding grooves 318, a plurality of drainage grooves 319, and a plurality of drainage holes 320, and the water guiding groove 317 and the water guiding groove 318 and the drainage groove 319. The structure can be exposed to the display surface 321 of the panel 31 to form an open space. Of course, in other preferred embodiments, the through hole 316, the water guiding groove 317, the water guiding groove 318, the drainage groove 319, and the drainage hole 320 may be embedded in the panel 31 to form a closed space. To illustrate, the invention is not limited thereto.

The through hole 316 can be disposed at the top end of the panel 31, and the water guiding groove 317 can be disposed between the through hole 316 and the display 33. Each of the water guiding holes 317 can be coupled to the corresponding through hole 316, and the water guiding groove 318 can be disposed on the panel 31. On the two sides of the display surface 321 , the respective water guiding grooves 318 can be connected to the corresponding water guiding grooves 317 , and the drainage grooves 319 are disposed on two sides below the display surface 321 of the panel 31 , and the respective drainage holes 319 can be connected to the corresponding water guiding grooves 318 . The drain holes 320 may be disposed on both sides of the lower side of the panel 31 and coupled to the corresponding drain grooves 319.

As shown in FIG. 9, the display surface 321 of the panel 31 generally covers the nameplate 36. Therefore, the nameplate 36 can be interposed between each of the through holes 316, the water guiding channel 317, the water guiding channel 318, the drain groove 319, and the drain hole 320. A closed space can be formed so that a drainage channel can be formed. When water or other liquid flows in through the through hole 316 above the panel 31, it first accumulates in the water guiding tank 317, flows into the drain groove 319 through the water guiding groove 318, and finally is discharged from both sides of the panel 31 via the drain hole 320. Through the above-described structural design, the water flowing into the inside of the human-machine interface device 30 through the through hole 316 of the panel 31 can be effectively discharged to protect the components such as the internal circuit board of the human-machine interface device 30 from being damaged. Of course, the drainage structure described in this embodiment is for illustrative purposes only, and the present invention is not limited thereto.

It is worth mentioning that the human-machine interface device of the prior art lacks proper drainage structure, so that water or other liquid can easily flow into the casing through the through hole in the panel, causing serious damage to important components such as the circuit board inside the device. Damage. In contrast, the present invention discloses a specially designed drainage structure disposed on the panel in the above embodiment, and the effect of effectively discharging the liquid flowing into the casing can be achieved through a simple and ingenious structural design to prevent damage to important components inside the device. It does improve the shortcomings of the traditional skills.

In summary, an embodiment of the present invention provides a plurality of fixing members and limiting members in the panel of the human-machine interface device, so that the display and the circuit board can be firmly fixed to the panel without passing through the metal frame or the screw. Between the back cover and the back cover, not only the assembly is more convenient, but also the manufacturing cost and the overall weight are greatly reduced. Moreover, in one embodiment of the present invention, a plurality of positioning members and limiting members are disposed in the cover of the human-machine interface device to further fix the position of the display and the circuit board, so that even if the human-machine interface device is subjected to an external force, the display and the display The board will not easily break away from its fixed area and cause significant damage. In addition, an embodiment of the present invention provides a special drainage structure on the panel of the human-machine interface device, thereby completely preventing water or other liquid from flowing into the interior of the human-machine interface device and causing damage to important components such as the circuit board.

It can be seen that the present invention has achieved the desired effect under the prior art, and is not familiar with the skill of the artist, and its progressiveness and practicability have been met with the patent application requirements.提出 Submit a patent application in accordance with the law, and ask your office to approve the application for this invention patent to encourage creation.
