AI Technical Summary
Traditional small-size LCD panels have problems such as dust accumulation, button failure and poor user experience in dustproof and key operation. Especially when the number of keys is less than that of LCD panels, complex software algorithms are required to solve the problem of mismatch between clicking keys and display content.
A switch with directionally pressed liquid crystal dust cover and buttons is designed. Through the combination of high-transmissive glass dust cover and plastic shrapnel, the wrap-around design of the LCD module and the touch switch is realized. The PCB guide ridge guides the movement of the high-transmissive glass dust cover. The user presses the top of the high-transmissive glass dust cover to achieve key operation, avoiding direct pressing of the touch switch.
It improves the visual effect and reliability of the device, extends the service life of the light-touch switch, reduces dust interference, simplifies equipment cleaning, and improves user experience.

[0001] The utility model relates to the field of small-size liquid crystal panel control switches, in particular to a switch with a directional pressing liquid crystal dust cover and a key integrated design. Background Art
[0002] Traditional small-sized non-touch LCD panels require clicking and selecting independent buttons to confirm the function when displaying the function on the screen. In addition, small-sized LCD panels are often dust-proofed with a high-transmittance glass dust cover that covers the entire LCD panel, with the mechanical buttons placed outside the dust cover. When the number of buttons is smaller than the LCD panel, complex software algorithms are required to solve the problem of mismatch between clicking buttons and displayed content, resulting in a poor user experience. In addition, the LCD, dust cover, and buttons are used separately, which is more likely to cause dust accumulation, which can easily cause button failure over time.

[0024] By providing a high-transmittance glass dust cover 1 and a plastic spring 4, the overall visual effect of the device is improved. The user no longer needs to press directly on the touch switch 6, thereby better extending the service life of the touch switch 6. The glass cover wraps the liquid crystal module, the plastic spring 4, and the touch switch 6 in an integrated design, which can better protect the device from dust interference, increase the reliability of the device, and make it easier to clean the surface of the device.
[0025] Reference Figure 1-Figure 5 As shown, multiple high-transmittance glass dust covers 1 extend to the interior of the product housing 5, and the lower sides of the left and right edges of multiple liquid crystal display modules 2 are fixedly connected to PCB guide ridges 3.
[0026] By providing the PCB guide ridge 3 , the high-transmittance glass dust cover 1 can be guided, so that the high-transmittance glass dust cover 1 can move downward when pressed and move upward under the rebound effect of the plastic spring 4 .
[0027] Reference Figure 1-Figure 5 As shown, the PCB guide ridge 3 is slidably connected to the high-transmittance glass dust cover 1, and the high-transmittance glass dust cover 1 is embedded in the PCB guide ridge 3.
[0028] Reference Figure 1-Figure 5 As shown, a plurality of liquid crystal display modules 2 are arranged at equal intervals, and a plurality of high-transmittance glass dust covers 1 are arranged at equal intervals.
[0029] Reference Figure 1-Figure 5 As shown, a PCB circuit board 8 is fixedly connected to the interior of the product housing 5 , a plurality of support columns 7 are fixedly connected to the upper end of the PCB circuit board 8 , and the upper ends of the plurality of support columns 7 are all fixedly connected to the plastic springs 4 .

[0032] Specific implementation process: The processor and other electrical components are integrated on the PCB circuit board 8. When the LCD module 2 displays a function option, the user selects the function and presses the top of the high-transmittance glass dust cover 1 with a finger. At this time, the high-transmittance glass dust cover 1 moves vertically downward under the pressure of the finger and pushes the plastic spring 4 to produce buckling deformation. When this deformation reaches a certain amplitude, it triggers the touch switch 6 at the bottom to close. The touch switch 6 generates an electrical signal to notify the processor that the user has pressed the button, completing the triggering action;
[0033] When the user completes the function selection and lifts his finger, the plastic spring 4 recovers its deformation without external force, pushing the high-transmittance glass dust cover 1 upward to its initial position. At this time, the touch switch 6 is disconnected and generates an electrical signal to notify the processor that the user's finger has left, completing the reset action.
