Description

Technical Field

[0001] This application belongs to the field of keyboard key technology and relates to a long key structure. Background Technology

[0002] In keyboard manufacturing, long keys (such as the spacebar, Enter key, and Shift key) require a scissor-switch mechanism due to their larger key surface size to ensure stable keycap pressing and return. Traditional scissor-switch mechanisms consist of a pair of cross-hinged links that guide the vertical travel of the keycap and distribute lateral stress during keystrokes. However, existing scissor-switch mechanisms generally suffer from the inherent limitation of non-adjustable length, resulting in poor compatibility and adaptability.

[0003] The length of the scissor-switch lever is strongly correlated with the keycap size, and its fixed design forces manufacturers to develop dedicated molds and components for long keys of different specifications. For example, for long keys on ultra-thin laptop keyboards and full-size external keyboards, scissor-switch lever structures of different lengths need to be designed separately, significantly increasing R&D costs and supply chain management complexity.

[0004] Therefore, how to provide a long button structure that maintains the stability advantage of the existing scissor-type buttons while overcoming the constraint of non-adjustable length, and achieving synergistic optimization of compatibility and assembly tolerance has become an urgent technical problem to be solved. Utility Model Content

[0005] To overcome the problems existing in related technologies, this application aims to provide a long button structure that can maintain the stability advantages of existing scissor-type buttons while breaking through the constraint of non-adjustable length, and achieve synergistic optimization of compatibility and assembly tolerance.

[0006] This application is achieved through the following technical solution.

[0007] This technical solution provides a long button structure, including:

[0008] The base plate has, in sequence, a trigger, scissor feet, an elastomer, and keycaps.

[0009] The scissor-foot mechanism includes an outer scissor-foot bracket and an inner scissor-foot bracket. The connecting sides of both the outer and inner scissor-foot brackets are configured to be connected to the base plate and the keycap respectively via a first snap-fit ​​mechanism and a second snap-fit ​​mechanism.

[0010] The scissor-leg outer bracket includes a connector and an assembly. The connector has a through hole for installing an elastomer, and the scissor-leg inner bracket is rotatably connected to the mounting groove of the assembly via a rotating shaft.

[0011] The connectors are configured in various specifications to fit the specific key dimensions of the buttons;

[0012] The connectors and assemblies are connected by a positioning mechanism.

[0013] This technical solution strengthens the overall structural strength of the button by using alloy connectors and reinforcing rods. The length of the scissor legs can be adjusted by replacing connectors of different sizes. It also ensures that pressing the button at any position will trigger the electrical action by pressing down the elastic body. In addition, there is no need to install a balance bar, thus avoiding impact noise between the balance bar and the base plate.

[0014] The present invention is further configured such that the positioning mechanism consists of a positioning hole and a connecting rod;

[0015] Both ends of the connector are provided with positioning holes, and the end of the assembly that connects to the connector is provided with a connecting rod corresponding to the positioning hole;

[0021] The present invention is further configured such that the assembly has shaft holes at both ends of the mounting groove corresponding to the rotating shaft, and the rotating shaft is rotatably connected to the inside of the shaft holes;

[0022] The inner bracket of the scissor leg is equipped with a protective pad and a limiting block, and the assembly parts have a limiting groove corresponding to the limiting block;

[0023] When the protective pad comes into contact with the keycap, the inner bracket of the scissor foot moves to the first end point of the rotation stroke. When the limit block comes into contact with the inside of the limit groove, the inner bracket of the scissor foot moves to the second end point of the rotation stroke.

[0024] The present invention is further configured such that the first snap-fit ​​mechanism comprises a base plate snap-fit, a keycap snap-fit, a first base plate pivot, and a second keycap pivot.

[0025] The base plate has a base plate clip, and the side of the keycap that is close to the base plate has a keycap clip corresponding to the side of the base plate clip.

[0042] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0044] This embodiment discloses a long button structure, such as Figures 1-7 As shown, it includes:

[0045] The base plate 1 is provided with a trigger 2, a scissor switch, an elastomer 5 and a keycap 6 in sequence. The trigger 2 and the elastomer 5 are both existing technologies.

[0046] The scissor feet include an outer scissor feet bracket 3 and an inner scissor feet bracket 4. The connecting sides of the outer scissor feet bracket 3 and the inner scissor feet bracket 4 are respectively configured to be connected to the base plate 1 and the keycap 6 through a first snap-fit ​​mechanism and a second snap-fit ​​mechanism.

[0047] The scissor-leg outer bracket 3 includes a connector 31 and an assembly 32. The connector 31 has a through hole 311 for installing the elastic body 5. The scissor-leg inner bracket 4 is rotatably connected to the mounting groove 328 of the assembly 32 via a rotating shaft 43.

[0048] Among them, the connector 31 is configured in various specifications to adapt to the specific key size of the button;

[0049] The connector 31 and the assembly 32 are connected by a positioning mechanism, and the connector 31 is made of alloy material.

[0050] It should be noted that the scissor-foot outer bracket 3 is divided into two parts: connector 31 and assembly 32. Connector 31 can be designed to be of different lengths according to the length of the long keys of different keyboards, and then cooperate with assembly 32 to form scissor-foot outer brackets 3 of different specifications. The scissor-foot inner bracket 4 is always installed in conjunction with assembly 32. Neither of them needs to be adjusted, which significantly reduces R&D costs and supply chain management complexity.

[0051] When pressing a portion of keycap 6, the scissor-switch pins connected to keycap 6, through an integrated design, allow the entire keycap 6 to be pressed down, creating a comfortable pressing feel.

[0052] Meanwhile, compared to the currently used lever-type scissor mechanism, the structure composed of the outer scissor bracket 3 and the inner scissor bracket 4 has higher strength, which can further reduce the thickness of the scissor mechanism, allowing the button to be made thinner.

[0053] like Figure 2 and Figure 5 As shown, the positioning mechanism consists of a positioning hole 314 and a connecting rod 327;

[0054] Both ends of the connector 31 are provided with positioning holes 314, and the end of the assembly 32 that is connected to the connector 31 is provided with a connecting rod 327 corresponding to the positioning hole 314.

[0055] The connecting rod 327 is fixed inside the positioning hole 314.

[0056] It should be noted that the positioning mechanism is sufficient to achieve a stable connection between the assembly 32 and the connector 31.

[0057] like Figure 2 and Figure 5 As shown, the positioning mechanism is a combination of toothed groove fit, positioning hole 314 and connecting rod 327.

[0058] like Figure 2 and Figure 5 As shown, the tooth groove fit can be a triangular tooth groove fit, a rectangular tooth groove fit, a trapezoidal tooth groove fit, or a V-groove fit;

[0059] Both ends of the connector 31 are provided with connecting grooves 313 and positioning holes 314 are provided through them. The connecting ends of the assembly 32 and the connector 31 are provided with connecting teeth 326 and connecting rods 327 corresponding to the connecting grooves 313 and positioning holes 314.

[0060] The connecting tooth 326 and the connecting groove 313 form a tooth-groove fit, and the connecting rod 327 is fixed inside the positioning hole 314.

[0061] It should be noted that the toothed groove fit achieves the positioning and fixing of the connector 31 and the assembly 32 through the engagement of the teeth and grooves.

[0062] like Figure 3 As shown, the assembly 32 has shaft holes 323 at both ends of the mounting groove 328 corresponding to the rotating shaft 43, and the rotating shaft 43 is rotatably connected to the inside of the shaft holes 323.

[0063] The inner bracket 4 of the scissor foot is provided with a protective pad 325 and a limiting block 44, and the assembly 32 is provided with a limiting groove 324 corresponding to the limiting block 44;

[0064] When the protective pad 325 comes into contact with the keycap 6, the inner bracket 4 of the scissor foot moves to the first end point of the rotation stroke. When the limit block 44 comes into contact with the inside of the limit groove 324, the inner bracket 4 of the scissor foot moves to the second end point of the rotation stroke.

[0065] It should be noted that the assembly 32 is also provided with a protective pad 325, which is used to limit its rotation stroke and at the same time, to prevent direct collision between structures.

[0066] like Figures 2-4 As shown, the first locking mechanism consists of a base plate latch 11, a keycap latch 61, a first base plate pivot 321, and a second keycap pivot 322.

[0067] The base plate 1 is provided with a base plate buckle 11, and the keycap 6 is provided with a keycap buckle 61 on the side of the base plate 1 corresponding to the side of the base plate buckle 11. The assembly 32 is provided with a first base plate post 321 corresponding to the base plate buckle 11, and the scissor-switch inner bracket 4 is provided with a second keycap post 322 corresponding to the keycap buckle 61.

[0068] like Figures 2-4 As shown, the second snap-fit ​​mechanism consists of a base plate hook 12, a keycap hook 62, a first keycap pivot 312, a second keycap pivot 322, and a second base plate pivot 42.

[0069] The base plate 1 is provided with a base plate hook 12. The keycap 6 is provided with a keycap hook 62 on the side of the base plate 1 that is close to the base plate 1 and the side where the base plate hook 12 is located. The connector 31 and the assembly 32 are respectively provided with a first keycap post 312 and a second keycap post 322 corresponding to the keycap hook 62. The scissor-foot inner bracket 4 is provided with a second base plate post 42 corresponding to the base plate hook 12.

[0070] The first keycap post 312, the second keycap post 322, and the second base plate post 42 are respectively engaged inside the corresponding keycap hook 62 and base plate hook 12, and can be displaced under the constraint of the keycap hook 62 and base plate hook 12.

[0071] It should be noted that, through the first and second locking mechanisms, when the keycap 6 is pressed, the scissor legs retract, causing the keycap 6 to squeeze the elastic body 5. Then, the elastic body 5 releases and squeezes the trigger 2, and the elastic body 5 drives the scissor legs to rebound, causing the keycap 6 to reset and realize the key function.

[0072] like Figure 2 As shown, the trigger 2 is provided with a reserved slot 21.

[0073] like Figure 2 As shown, the top of the elastic body 5 abuts against the keycap 6, and the bottom abuts against the trigger 2.

[0074] like Figure 4 As shown, the keycap 6 has a buckle 63 along its length, and a reinforcing rod 64 is engaged inside the buckle 63.

[0075] It should be noted that the reinforcing rod 64 is made of alloy material and is fastened to the keycap 6 to strengthen the keycap 6.

[0076] Working principle: The overall structural strength of the button is enhanced by the alloy connector 31 and the reinforcing rod 64. The length of the scissor legs can be adjusted by replacing the connector 31 with different sizes. At the same time, it can be ensured that pressing the button at any position will trigger the electric current by pressing down the elastic body 5. In addition, there is no need to install a balance bar, thus avoiding the impact noise between the balance bar and the base plate 1.
