[0027] According to a specific embodiment of this disclosure, refer to Figures 1 to 6 As shown, a control panel assembly is provided, including: a panel base 1, which is integrally molded and has a mounting cavity 11. The panel base 1 includes a back plate 12, which is disposed opposite to a first opening 13 of the mounting cavity 11 and has a second opening 14; a panel box 2, which is disposed in the mounting cavity 11 and connected to a wire harness 5; a display panel 3, which covers the first opening 13 and is sealed to the panel base 1; and a cover plate 4, which covers the second opening 14 and is sealed to the back plate 12. A wire passage groove 41 is formed on the cover plate 4, and the wire harness 5 passes through the second opening 14 and passes through the wire passage groove 41.

[0028] Through the above technical solution, in the control board assembly provided in this disclosure, the control board assembly is assembled by placing the board box 2 inside the mounting cavity 11 and covering the first opening 13 with the display panel 3. The wiring harness 5 of the board box 2 extends out of the panel base 1 through the second opening 14 for connection with external electrical components. Since the panel base 1 is a one-piece molded part, only sealing is required between the display panel 3 and the panel base 1 at the first opening 13, and between the cover plate 4 and the back plate 12 at the second opening 14, to achieve overall sealing of the control board assembly. Furthermore, the cover plate 4 seals the second opening 14, facilitating sealing operations, improving sealing efficiency, and allowing for easy maintenance by removing and installing the cover plate 4. The wiring harness 5 is placed in the wire guide 41 to secure it, reducing the risk of wear and damage. This reduces the number of sealing interfaces in the control board assembly, simplifies the sealing process, and lowers manufacturing costs.

[0029] According to the embodiments provided in this disclosure, refer to Figure 1 and Figure 2 As shown, the board box 2 includes a circuit board 21, which is partially exposed in the second opening 14. The portion of the circuit board 21 exposed in the second opening 14 is provided with at least one plug-in terminal, which is connected to the wiring harness 5. In this way, the plug-in terminal can be exposed in the second opening 14 so that the wiring harness 5 can be plugged into the plug-in terminal through the second opening 14 to achieve an electrical connection between the wiring harness 5 and the plug-in terminal.

[0030] According to the embodiments provided in this disclosure, refer to Figure 1 and Figure 2 As shown, the area of ​​the second opening 14 is smaller than the projected area of ​​the circuit board 21 in its thickness direction. This allows the wire harness 5 to be connected to the plug-in terminal by aligning it with the second opening 14, facilitating rapid positioning during the connection process and improving connection efficiency and ease of operation. Simultaneously, by setting the area of ​​the second opening 14 to fit the size of the plug-in terminal, the connection requirements of the wire harness 5 can be met, which helps reduce the sealing area of ​​the sealing region on the back plate 12, thereby reducing the amount of sealing material used and improving sealing efficiency and performance.

[0031] According to the embodiments provided in this disclosure, refer to Figure 2 and Figure 4 As shown, a sealing ring 7 is provided between the cover plate 4 and the panel seat 1. The sealing ring 7 is used to provide a seal at the connection between the cover plate 4 and the panel seat 1. In this way, the sealing ring 7 can fill the gap between the cover plate 4 and the panel seat 1, preventing dust or liquid from entering the mounting cavity 11 and damaging the circuit board 21. At the same time, the sealing ring 7 can provide a buffering effect between the cover plate 4 and the panel seat 1, preventing the cover plate 4 from loosening when subjected to vibration or impact, thus affecting the sealing effect.

[0032] According to the embodiments provided in this disclosure, refer to Figures 1 to 4 As shown, one of the cover plate 4 and the panel seat 1 is equipped with a snap fastener 42, and the other is equipped with a slot 15. The snap fastener 42 engages with the slot 15, and a sealing ring 7 is disposed on the inner side of the snap fastener 42 and the slot 15. In this way, the snap fastener 42 and the slot 15 can be used to install and fix the cover plate 4, improving the assembly efficiency of the control panel assembly. Furthermore, the snap fastener 42 and the slot 15 provide a stable mechanical connection to ensure the reliability of the connection between the cover plate 4 and the panel seat 1, reducing the risk of the cover plate 4 becoming loose due to impact or vibration. Simultaneously, by disposing of the sealing ring 7 on the inner side of the snap fastener 42 and the slot 15, the sealing ring 7 can be evenly stressed when the snap fastener 42 and the slot 15 are engaged, ensuring a good seal between the cover plate 4 and the panel seat 1.

[0033] According to the embodiments provided in this disclosure, refer to Figure 1 and Figure 6 As shown, a sealing cotton 6 is provided in the wire passage groove 41. The sealing cotton 6 has a wire passage hole, through which the wire harness 5 passes. The sealing cotton 6 is used to provide a seal between the wire harness 5 and the wire passage groove 41. In this way, the sealing cotton 6 covers the circumference of the wire harness 5. Thus, when the wire harness 5 is placed in the wire passage groove 41, the sealing cotton 6 can seal the gap between the wire harness 5 and the cover plate 4, preventing dust and moisture from entering. In addition, the sealing cotton 6 can also protect the wire harness 5, preventing wear between the wire harness 5 and the cover plate 4 or the panel seat 1, or the wire harness 5 from being squeezed, which would affect the reliability of the electrical connection.

[0034] According to the embodiments provided in this disclosure, refer to Figure 1 and Figure 4 As shown, a buzzer is installed on the box 2, and a positioning post 43 is provided on the inner side of the cover 4. A sound-transmitting hole 44 is opened on the positioning post 43, and the sound-transmitting hole 44 is directly opposite the buzzer. In this way, by setting the positioning post 43 so that the position of the sound-transmitting hole 44 is directly opposite the buzzer, the sound-transmitting hole 44 can provide a transmission path for the sound emitted by the buzzer. Thus, the setting of the cover 4 can be avoided from affecting the sound output of the buzzer.

[0035] According to the embodiments provided in this disclosure, refer to Figure 1 , Figure 2 and Figure 5As shown, the control panel box 2 includes a bracket 22, a circuit board 21, and a color filter film 23.
