Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work shall fall within the scope of protection of the present invention.

[0039] Embodiment 1: The embodiment of the present invention provides a touch panel structure, such as Figures 1 to 4 As shown in the figure, the touch panel structure includes: an external frame 1; an internal frame 2, which is arranged in the external frame 1; a touch panel 3, which is arranged on the outside of the external frame 1; a PCB assembly, including an electrically connected low-voltage module 4 and a high-voltage module 5; an anti-static partition 6, which is located in the external frame 1 and connected to the internal frame 2, and is used to separate the low-voltage module 4 and the high-voltage module 5; wherein, the low-voltage module 4 is arranged on the anti-static partition 6 and is located on the side of the anti-static partition 6 close to the touch panel 3; the high-voltage module 5 is arranged in the internal frame 2 and is located on the side of the anti-static partition 6 away from the touch panel 3.

[0040] The touchpad structure of the embodiment of the present invention adopts an embedded safety isolation layout, separating the low-voltage module 4 and the high-voltage module 5 by an anti-static partition 6, so that the low-voltage module 4 and the high-voltage module 5 are respectively located on both sides of the anti-static partition 6. Based on this layered structure design, it has a certain physical protection effect on the PCB components and also has a good anti-static effect.

[0041] In this embodiment, two opposing inner sidewalls of the outer frame 1 are each embedded with a plurality of spring-loaded positioning beads 7 for fastening and securing the inner frame 2. Specifically, the inner frame 2 is provided with two retaining walls 21, correspondingly parallel to the two opposing inner sidewalls of the outer frame 1, to facilitate assembly and positioning of the inner frame 2. Each retaining wall 21 is provided with a positioning groove 210 or a positioning hole into which a corresponding spring-loaded positioning bead 7 snaps in. This snap-fit connection between the inner frame 2 and the outer frame 1, achieved by the snap-fit structure of the spring-loaded positioning beads 7, facilitates use and transportation, provides excellent assembly stability, and replaces existing magnetic structures, meeting air transport requirements.

[0042] In this embodiment, the outer frame 1 is made of an anodized aluminum alloy. The oxide film formed by anodization makes the outer frame 1 have good wear resistance, corrosion resistance and electrical insulation, and has better performance. The aluminum alloy material is specifically aluminum alloy 6063, for example.

[0043] Among them, the touch panel 3 is embedded in the outer surface of the external frame 1. The touch panel 3 is made of, for example, tempered glass material, and the tempered glass panel has high strength and good safety; the anti-static partition 6 is made of, for example, PC-ABS composite material, and the anti-static partition has good anti-static performance; the internal frame 2 is made of, for example, A3 steel spray paint material, which has good mechanical properties and good weather resistance.

[0044] In this embodiment, two opposing inner sidewalls of the internal frame 2 are provided with a plurality of first latching slots 201, and the high-voltage module 5 is provided with a plurality of wedge-shaped locking blocks 51. The plurality of wedge-shaped locking blocks 51 are locked in a one-to-one correspondence with the plurality of first latching slots 201, thereby achieving an assembly connection between the internal frame 2 and the high-voltage module 5, facilitating assembly and disassembly and ease of use. Furthermore, two opposing inner sidewalls of the internal frame 2 are provided with a plurality of second latching slots 202, and the high-voltage module 5 is further provided with a plurality of rectangular positioning blocks 52. The plurality of rectangular positioning blocks 52 are locked in a one-to-one correspondence with the plurality of second latching slots 202, facilitating rapid positioning of the internal frame 2 and the high-voltage module 5 during assembly, thereby quickly locking the internal frame 2 and the high-voltage module 5 into place.

[0045] Specifically, a surrounding wall 53 is provided at the edge of one side surface of the high-voltage module 5 located within the internal frame 2. Two opposing side walls of the surrounding wall 53 correspond to two opposing inner side walls of the internal frame 2, and are each provided with a wedge-shaped locking block 51 that engages with a corresponding first latching slot 201. The other two opposing side walls of the surrounding wall 53 correspond to two opposing inner side walls of the internal frame 2, and are each provided with a rectangular positioning block 52 that engages with a corresponding second latching slot 202. The surrounding wall 53 provides suitable space for the wedge-shaped locking block 51 and the rectangular positioning block 52 without affecting the structure of the high-voltage module 5.

[0046] In this embodiment, the high-voltage module 5 is further provided with an electrical connection terminal 54 on one side surface within the internal frame 2 for electrical connection with the low-voltage module 4. The anti-static baffle 6 is correspondingly provided with a clearance hole 601 through which the power connection terminal 54 passes. The low-voltage module 4 is connected to the anti-static baffle 6 via a snap and / or screw connection. Once the internal frame 2 and the high-voltage module 5 are assembled, the electrical connection terminal 54 is inserted into the clearance hole 601, thereby achieving electrical connection with the low-voltage module 4.

[0047] In this embodiment, the PCB component, such as the touch switch module, that is, the touch switch module includes an electrically connected low-voltage module 4 and a high-voltage module 5. The specific structural layout of the low-voltage module 4 and the high-voltage module 5 can be designed and selected according to actual application needs, and this embodiment does not make specific limitations.

[0048] It should be noted that, in other embodiments, the PCB assembly can also be expanded into one or a combination of the following functional modules: touch temperature control module 100; socket module 200; card plug-in power module 300. Among them, the structure of the touch temperature control module 100 is as follows: Figure 5 As shown; the structure of the socket module 200 is as shown Figure 6 As shown; the structure of the card power module 300 is as shown Figure 7 It should be noted that the structures of the touch temperature control module 100, the socket module 200 and the card-insertion power module 300 shown in the drawings are only examples and do not constitute specific limitations. In actual applications, they can be designed and selected according to actual application needs.

[0049] It is understandable that, in actual application, the touch panel 3 should also be adaptively adjusted according to the selected PCB components of different functional modules to meet the corresponding actual application requirements. Figure 1 The structure of the touch panel 3 shown is only an example of a specific implementation structure when it is adapted for use with the touch switch module, and does not constitute a specific limitation.
