[0042] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0043] Please see below. Figures 1 to 8 The present invention provides a long key scissor-switch module, which specifically includes an outer scissor 10, a long inner scissor 20, a short inner scissor 30, a keycap 40, and a mounting base plate 50.

[0044] The outer shear 10 is provided with a middle mounting groove 11 and an end mounting groove 12. The long inner shear 20 is installed in the middle mounting groove 11, and the short inner shear 30 is installed in the end mounting groove 12.

[0045] One side of the outer shear 10 and one side of the short inner shear 30 are respectively fastened to the mounting base plate 50, and the side of the short inner shear 30 that is fastened to the mounting base plate 50 is away from the side of the outer shear 10 that is fastened to the mounting base plate 50.

[0046] The keycap 40 covers the outer cutter 10, the long inner cutter 20, the short inner cutter 30 and the mounting base plate 50. The keycap 40 is provided with multiple fastening parts, which fasten to the outer cutter 10, the long inner cutter 20 and the short inner cutter 30 respectively.

[0047] In this embodiment, by setting a multi-layered locking structure with outer and inner shears, the keycap 40 can be stably fixed and responsive without the need for a stabilizer bar. This effectively avoids noise caused by the impact of the stabilizer bar, increases support for the keycap 40, improves the poor feel caused by the excessive length of the keycap 40, enhances the downward pressure feel, and improves the overall user experience.

[0048] In one embodiment, the fastening part includes a first fastening part 41, a second fastening part 42 and a third fastening part 43 with protrusions. The first fastening part 41 and the second fastening part 42 are respectively disposed on both sides of the bottom surface of the keycap 40, and the third fastening part 43 is disposed between the first fastening part 41 and the second fastening part 42.

[0049] The first fastening part 41 fastens to the outer shear 10, the second fastening part 42 fastens to the long inner shear 20, and the third fastening part 43 fastens to the short inner shear 30.

[0050] In this embodiment, the keycap 40 engages with the outer cutter 10, the long inner cutter 20, and the short inner cutter 30 through multiple snap-fit ​​parts, thereby achieving a tighter structural connection, enhancing the synergy between the components, and improving the keycap 40's pressing feel and rebound feel.

[0051] In a specific embodiment, multiple first engaging parts 41, second engaging parts 42, and third engaging parts 43 are provided, and each of the first engaging parts 41, second engaging parts 42, and third engaging parts 43 is symmetrically distributed to ensure uniform force on the keycap 40 and further optimize the feel. For example, four second engaging parts 42 are provided and arranged in an array on one side of the keycap 40. The second engaging parts 42 achieve a tight connection and coordinated action between the keycap 40 and the long inner shear 20, thereby realizing the linkage effect between the long inner shear 20 and other components such as the short inner shear 30, ensuring the stability and consistency of the keycap 40 under different pressures. It is understood that the number, shape, size, and distribution of each engaging part can be adjusted according to actual needs to adapt to the structural characteristics of different keycaps 40 and scissor-switch modules.

[0052] In one embodiment, a first mounting portion 31 for fastening the mounting base plate 50 is provided on one side of the short inner shear 30, and a second mounting portion 32 for fastening the keycap 40 is provided on the other side.

[0053] Preferably, a first mounting post 33 is provided in the middle of the side of the short inner shear 30, and a first mounting hole 121 is provided on the inner side wall of the end mounting groove 12. The first mounting post 33 is inserted into and rotated in the first mounting hole 121.

[0054] In this embodiment, by providing a first mounting part 31 and a second mounting part 32 on both sides of the short inner scissor 30, a stable connection between the short inner scissor 30 and the mounting base plate 50 and the keycap 40 is ensured. The cooperation between the first mounting post 33 and the first mounting hole 121 enables flexible rotation between the short inner scissor 30 and the mounting base plate 50. This utilizes the elastic and synergistic characteristics of the scissor-type structure to optimize the pressing feel and rebound effect of the keycap 40.

[0055] In one embodiment, the end mounting groove 12 is completely embedded inside the mounting base plate 50, and all four sides of the end mounting groove 12 are closedly connected to the mounting base plate 50.

[0056] Two short inner shears 30 are provided, and the two short inner shears 30 are respectively installed in the end mounting grooves 12 at both ends of the outer shear 10.

[0057] In this embodiment, the design of the end mounting groove 12 ensures a tight fit between the short inner scissor 30 and the outer scissor 10. By setting two short inner scissors 30 and embedding them into the end mounting grooves 12 at both ends of the outer scissor 10, the corner linkage of the keycap 40 is improved, thereby evenly transmitting the force of pressing the keycap 40 to the entire keycap 40 structure.

[0058] In one embodiment, the intermediate mounting groove 11 includes an open side and a closed side disposed opposite to each other, the open side facing the side where the outer shear 10 is fastened to the mounting base plate 50, and the long inner shear 20 is mounted on the closed side.

[0059] A third mounting part 21 for fastening the keycap 40 is provided on one side of the long inner shear 20, and a second mounting post 22 is provided on the opposite side. A second mounting hole 111 is provided on the inner wall of the middle mounting groove 11. The second mounting post 22 is inserted into and rotated in the second mounting hole 111.

[0060] Among them, the long inner shear 20 is provided with the third mounting part 21 on one side corresponding to the open side, and the second mounting post 22 is provided with the second mounting part on one side corresponding to the closed side.

[0061] In this embodiment, the long inner shear 20 is rotatably mounted on the closed side of the middle mounting groove 11 through the cooperation of the second mounting post 22 and the second mounting hole 111, ensuring a stable connection between the long inner shear 20 and the outer shear 10. Through the tight engagement of the third mounting part 21 with the keycap 40, the coordinated action of the long inner shear 20 and the keycap 40 is realized. Furthermore, by combining the linkage effect of the long inner shear 20 and the short inner shear 30, the pressing force can be distributed to the four corners and the center of the keycap 40, reducing local pressure concentration and improving the response speed and stability of the keycap 40 under different pressures, improving the consistency of the feel, thereby optimizing the user's operating experience.

[0062] In one embodiment, the mounting base plate 50 is provided with protruding hooks 51 for fastening the outer shear 10 and the short inner shear 30 respectively.

[0063] In this embodiment, the mounting base plate 50 is precisely connected to the outer shear 10 and the short inner shear 30 through the hook buckle 51, which enhances the stability of the overall structure, ensures that the components are not easily loosened during frequent use, and further improves the durability of the keycap 40.

[0064] In a specific embodiment, the number and position of the hook buckles 51 are optimized according to the specific size and layout of the outer shear 10 and the short inner shear 30, ensuring that each hook buckle 51 can effectively fix the corresponding component, thereby maximizing the overall installation's firmness and reliability while maintaining a compact structure.

[0065] In one embodiment, the outer shear 10 has a first fastening part 13 on one side for engaging with the hook buckle 51, and a second fastening part 14 on the other side for engaging with the fastening part.

[0066] In this embodiment, the outer shear 10 achieves precise docking with the hook buckle 51 and the fastening part by setting the first fastening part 13 and the second fastening part 14 on both sides, thereby achieving a stable connection with the mounting base plate 50 and the keycap 40, ensuring that the components work together during operation.

[0067] It is understandable that the number and position of the first snap-fit ​​part 13 and the second snap-fit ​​part 14 can also be flexibly adjusted according to the specific size and layout of the outer clip 10 so that the outer clip 10 can achieve the best fit with the mounting base plate 50 and the keycap 40.

[0068] In one embodiment, the long-button scissor-switch module further includes an elastic element 60 disposed between the mounting base 50 and the keycap 40.

[0069] Preferably, the elastic element 60 is located at the middle position of the mounting base plate 50, and the outer shear 10 is provided with a through hole for mounting the elastic element 60 at the corresponding position.

[0070] In this embodiment, by setting an elastic element 60 at the middle position of the mounting base plate 50 and placing it between the mounting base plate 50 and the keycap 40, the elastic element 60 can provide elastic force to effectively buffer the impact force of the keycap 40 during the pressing process, reduce wear, extend service life, and achieve the rebound of the keycap 40 through elastic force, ensuring that the key feedback is rapid and stable.

[0071] In specific application scenarios, the material of the elastic element 60 can be selected according to actual needs. For example, it can be made of elastic materials such as silicone, or a spring can be used as the elastic element 60, etc.

[0072] Based on the setting of elastic element 60, such as Figure 7 As shown, the elastic force of the elastic element 60, combined with the action of each connecting structure, can synchronously lift the outer shear 10, the long inner shear 20, the short inner shear 30, and the keycap 40 (not shown in the figure), forming a scissor-leg structure. Figure 8 As shown, when keycap 40 is pressed, the elastic element 60 compresses and stores energy. Simultaneously, the various connecting structures work together, distributing pressure to the outer shear 10, long inner shear 20, and short inner shear 30 via the scissor-switch mechanism. This achieves balanced force distribution and presses the key down as a whole, ensuring smooth and seamless key operation. It also effectively reduces key noise, making the operation quieter and further enhancing the user experience. After keycap 40 is released, the elastic element 60 restores its deformation and releases energy, causing keycap 40 to quickly spring back to its initial position. All components work together to reset, ensuring sensitive key response and smooth operation for the next press.

[0073] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple; relevant parts can be referred to in the method section. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.

[0074] It should also be noted that, in this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
