Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a back panel structure, a button module and a keyboard. Background Technology

[0002] During the assembly of a scissor-switch keyboard, the sharp edges of the backplate make the scissor assembly susceptible to scratches when installed, potentially causing localized damage. For example... Figure 5-8 As shown, the scratched area is precisely where the keycap height is limited. This defect can cause an abnormal increase in the overall keycap height, thus affecting the keyboard's overall performance and user experience. Summary of the Invention

[0003] Purpose of the utility model: This utility model aims to provide a backplate structure, key module, and keyboard that prevents over-cutting during the assembly of scissor-switch keys and effectively controls the height of the keycaps.

[0004] Technical solution: The back plate structure of this utility model has a mounting part for mounting a scissor assembly. The mounting part includes a scraping part for scraping the scissor assembly and at least one height limiting part.

[0005] Furthermore, the scraping part, the height limiting part, and the back plate are integrally formed. This design not only improves the stability and reliability of the structure but also simplifies the manufacturing process.

[0006] Furthermore, the connection between the scraping part and the height limiting part has a smooth arc transition to reduce stress concentration and improve the durability of the structure.

[0007] In addition, the edges of the scraping part and / or the height limiting part are rounded to reduce scraping wear.

[0008] Based on the aforementioned backplate structure, this utility model also proposes a button module, including a backplate, a scissor assembly, and keycaps, wherein the backplate adopts the aforementioned backplate structure.

[0009] Furthermore, in the key module, the height limiting part of the back plate is used to limit the height of the keycaps, ensuring that the key module has stable feedback and consistent feel when pressed.

[0010] Finally, this utility model also proposes a keyboard that uses the above-mentioned key module.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The design of the mounting part of the present invention includes at least one height limiting position for limiting the height of the keycap, and the height limiting position does not coincide with the scraping position of the scissor assembly, thereby ensuring that the height of the keycap is not affected by the scraping of the scissor assembly.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0021] Example 1

[0022] like Figure 1-4 As shown, this embodiment provides a backplate structure. The backplate 1 is provided with a mounting part 11 for mounting the scissor assembly 2. The mounting part 11 includes a scraping part 111 for scraping the scissor assembly 2 and at least one height limiting part 112. The location where the scraping occurs is separated from the key position that limits the height of the keycap, thereby ensuring that the height of the keycap 3 remains stable and is not affected by the scraping phenomenon.

[0023] In some embodiments, the scraping portion 111 is designed with a slightly raised structure to increase the friction between it and the scissor assembly, ensuring that the scissor assembly can be stably fixed to the backplate 1 during installation. Simultaneously, the edges of the scraping portion 111 are rounded to reduce wear on the scissor assembly. The height limiting portion is designed as a columnar structure perpendicular to the backplate surface, and its height is precisely controlled according to the keycap design requirements. The top of the height limiting portion is flat, used to contact the bottom of the keycap, thereby limiting the height of the keycap. The edges of the height limiting portion are also rounded to reduce wear and improve tactile feedback.

[0024] Example 2

[0025] Based on the above-mentioned backplate structure, this embodiment also proposes a key module, including a backplate 1, a scissor assembly 2, and keycaps 3. The backplate 1 adopts the above-mentioned backplate structure. In the key module, the height limiting part 112 of the backplate 1 is used to limit the height of the keycaps 3, so as to ensure that the key module has stable feedback and consistent feel when pressed.

[0026] Example 3

[0027] This embodiment also proposes a keyboard that uses the above-described key module.
