[0032] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0033] [Example]

[0034] Combination Figures 1 to 7 As shown, this embodiment of an expandable PLC touch screen all-in-one machine includes a front frame 1, a rear cover 2, a middle frame 3, a touch screen assembly, a PLC control board 8, and a function circuit board 10. The touch screen assembly is mounted on the front frame 1, the middle frame 3 is mounted between the front frame 1 and the rear cover 2, and the PLC control board 8 and the function circuit board 10 are respectively mounted on the middle frame 3. At least one middle frame 3 is provided; when two or more middle frames 3 are provided, adjacent middle frames 3 are stacked together along their thickness direction. The number of middle frames 3 can be determined according to actual needs. That is, when additional functional modules are required, only the number of middle frames 3 needs to be increased to increase installation space, without the need for redesigning and molding the outer casing, greatly reducing repetitive development costs and improving the functional expandability of the PLC touch screen all-in-one machine. The PLC touch screen all-in-one machine of this embodiment can achieve modular assembly and can be customized and assembled into products with different functions according to user needs. Figures 1 to 4 The image shows a PLC touch screen all-in-one machine with a middle frame 3, which can achieve basically the same functions (mainly hardware functions) as products of the same size on the market; Figure 6 and Figure 7The diagram shows a PLC touch screen all-in-one machine with two middle frames 3. Additional functional modules can be added through the pre-drilled mounting holes on the middle frames 3 to enrich the functionality of the PLC touch screen all-in-one machine. Of course, the number of middle frames 3 is not limited to one or two; in principle, there is no limit to the number of middle frames 3. However, considering the product thickness and the number of additional functional modules that can be added, the number of middle frames 3 used will typically not exceed five.

[0035] Reference Figures 1 to 7 As shown, in this embodiment, the interfaces of the PLC control board 8 are all located on the side of the corresponding middle frame 3. This is significantly different from existing PLC touch screen all-in-one machines, which mostly place the interfaces on the back of the product. This requires high precision in the hole positions on the back cover and is prone to interference between wiring connections. In this embodiment, the interfaces of the PLC control board 8 are located on the side of the installed middle frame 3. This allows for flexible selection of the installation position of the PLC control board 8 on different middle frames 3, and the PLC interfaces are easy to set up and connect. Furthermore, there is more space for interface installation, resulting in a richer array of interfaces. Additionally, the interfaces of the PLC control board 8 are also equipped with external expansion terminals 9 for wiring. These terminals facilitate wiring operations and improve signal connection stability. Moreover, the PLC control board 8 also features a TF card slot, a PLC download interface, a touch screen download interface, and a network interface located on the side of the corresponding middle frame 3.

[0036] Reference Figure 5 As shown, in this embodiment, the middle frame 3 is provided with a middle frame connection hole 3-1, a PLC connection hole 3-2, and a circuit board connection hole 3-3. The middle frame 3 is screwed to the front frame 1 and the rear cover 2 through the middle frame connection hole 3-1. The PLC control board 8 is screwed to the middle frame 3 through the PLC connection hole 3-2. The functional circuit board 10 is screwed to the middle frame 3 through the circuit board connection hole 3-3. Specifically, the PLC connection hole 3-2 and the circuit board connection hole 3-3 can be self-tapping screw holes. The PLC control board 8 has screw holes corresponding to the position of the PLC connection hole 3-2, and the PLC control board 8 can be fixed to the middle frame 3 with screws. The functional circuit board 10 has screw holes corresponding to the position of the circuit board connection hole 3-3, and the functional circuit board 10 is also fixed to the middle frame 3 with screws. The middle frame connecting hole 3-1 can be a through hole, which corresponds to the screw hole position on the front frame 1 and the rear cover 2. Long screws can be used to pass through the middle frame connecting hole 3-1 of the middle frame 3 from the rear cover 2 and then tighten them onto the front frame 1.

[0037] return Figure 1As shown, in this embodiment, the touch screen assembly includes an interaction panel 4, a touch screen 5, and an LCD screen 6. The touch screen 5 and LCD screen 6 are installed sequentially from the outside to the inside of the front frame 1. The interaction panel 4 is attached to the front end surface of the front frame 1 and has a transparent display area, which can protect the touch screen 5 and LCD screen 6. In addition, unlike existing PLC touch screen all-in-one machines, this embodiment also has a screen retaining strip 7 installed on the back of the front frame 1, which abuts against the back of the LCD screen 6. Two screen retaining strips 7 can be provided, respectively located on both sides of the LCD screen 6. The two ends of the screen retaining strips 7 are fixed to the front frame 1 by screws.

[0038] In this embodiment, the front frame 1, rear cover 2, and middle frame 3 are all injection molded parts. By adding or subtracting the number of middle frames 3 between the front frame 1 and the rear cover 2, PLC touch screen all-in-one machines with different functions can be expanded. As for the specific circuit principles of the PLC control board 8 and the functional circuit board 10, as well as the circuit connection relationships and other interface settings of the PLC touch screen all-in-one machine, these are all existing technologies and will not be elaborated here.

[0039] This utility model discloses an expandable PLC touch screen all-in-one machine. By setting a middle frame between the front frame and the rear cover to install the PLC control board and function circuit board, when additional function modules are needed, only the middle frame needs to be added to meet the installation requirements. There is no need to repeatedly develop products with different functions, which reduces product development and production investment, effectively reduces product costs, shortens the product development cycle, and facilitates customized production according to user needs.

[0040] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
