Description

Technical Field

[0001] This utility model belongs to the field of keyboard key technology, specifically a keyboard structure that improves structural wobbling. Background Technology

[0002] The keyboard is the most important input device for a computer. Scissor-switch keys are a structural design used for keys on a keyboard. Their core function is to make the keys more stable, thinner, more consistent in feel, and quieter.

[0003] In the existing keyboard structure, please refer to Figure 4 As shown, a scissor-switch mechanism typically includes an inner scissor-switch leg and an outer scissor-switch leg, connected by a rotating shaft. One end of the inner scissor-switch leg has an inner scissor-switch shaft, and one end of the outer scissor-switch leg has an outer scissor-switch shaft. A hook on the support plate engages with these shafts. However, in the Y-axis direction, because the inner scissor-switch shaft needs to slide within the hook on the plate, while the outer scissor-switch shaft lacks effective restraint, it slides along with the inner scissor-switch shaft during pressing, causing overall structural wobbling. This wobbling is particularly noticeable in high-travel keyboards, affecting user experience and failing to meet the growing demands of users. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a keyboard structure that improves structural wobbling.

[0005] The technical solution adopted by this utility model is as follows: A keyboard structure to improve structural wobbling includes a scissor-leg mechanism and a supporting iron plate. The scissor-leg mechanism includes an outer scissor leg and an inner scissor leg connected to the outer scissor leg by a rotating shaft. One end of the outer scissor leg is provided with an outer scissor leg shaft, and the bottom of the outer scissor leg shaft is provided with a boss. The supporting iron plate is provided with a hole for the boss to extend into. When the scissor-leg mechanism is subjected to force and moves downward, the side of the boss abuts against the side wall of the hole to limit the movement state of the scissor-leg mechanism.

[0006] In a preferred embodiment, the boss is located at the bottom center of the outer scissor leg.

[0007] In a preferred embodiment, the thickness of the boss extending into the hole is at least 0.15 mm.

[0008] In a preferred embodiment, the width of the hole is greater than the width of the boss.

[0009] In a preferred embodiment, one end of the inner scissor foot is provided with an inner scissor foot shaft, and the supporting iron plate is provided with hook portions that engage with the inner scissor foot shaft and the outer scissor foot shaft.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] By setting a boss at the bottom of the outer scissor-switch hinge and creating a hole in the support plate, the boss will always be in contact with the side wall of the hole in the plate during the keycap pressing process. This restricts the entire structure to only vertical movement, with no offset in the Y direction. This effectively limits the sliding of the scissor-switch mechanism in the Y-axis direction, making the scissor-switch mechanism only able to rotate and not slide. This improves the problem of key wobbling when the keyboard keys are pressed, and enhances the stability and accuracy of the keys. Moreover, the overall structure is simple and is particularly suitable for high-travel keyboard structures. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] A keyboard structure to improve structural wobbling, refer to Figure 1-5 The system includes a scissor-leg mechanism 100 and a supporting plate 200. The scissor-leg mechanism 100 includes an outer scissor leg 120 and an inner scissor leg 110 connected to the outer scissor leg 120 via a rotating shaft. One end of the outer scissor leg 120 is provided with an outer scissor leg shaft 122, and the bottom of the outer scissor leg shaft 122 is provided with a boss 121. The supporting plate 200 has a hole 220 for the boss 121 to extend into. When the scissor-leg mechanism 100 is subjected to force and moves downward, the side of the boss 121 abuts against the side wall of the hole 220, thereby limiting the movement of the scissor-leg mechanism 100. In the motion state of 00, during the pressing of the keycap (not shown in the figure), the boss 121 will always be in contact with the side wall of the hole 220 of the supporting iron plate 200, thus restricting the entire structure to only move vertically and without offset in the Y direction. This effectively restricts the sliding of the scissor mechanism 100 in the Y-axis direction, so that the scissor mechanism 100 can only rotate and cannot slide. This improves the problem of keyboard keys shaking when pressed, improves the stability and accuracy of the keys, and the overall structure is simple, making it particularly suitable for high-travel keyboard structures.

[0026] The scissor mechanism 100 and the support plate 200 are assembled inside the keys of the keyboard. The specific assembly method and structure are existing known technologies and will not be described in detail here.

[0027] Specifically, the boss 121 is located at the bottom center of the outer scissor foot 120. The position design of the boss 121 ensures uniform force distribution, more stable limiting effect, and avoids additional shaking caused by eccentric force.

[0028] In this embodiment, the thickness of the boss 121 extending into the hole 220 is at least 0.15 mm. The above design ensures sufficient contact depth, avoids limit failure due to dimensional tolerance, and improves the reliability of the structure.

[0029] In this embodiment, one end of the inner scissor foot 110 is provided with an inner scissor foot shaft, and the supporting iron plate 200 is provided with hook parts 210 that engage with the inner scissor foot shaft and the outer scissor foot shaft 122.

[0030] In this embodiment, the width of the hole 220 is greater than the width of the boss 121. The above design allows for certain assembly tolerances, ensuring that the boss 121 can smoothly enter the hole 220 during the assembly process, while not affecting the limiting function, thus improving assembly convenience and production yield.

[0031] The assembly process of the scissor legs and the iron plate is as follows:

[0032] 1. The outer scissor foot shaft 122 slides into the hook part 210. The inside of the hook part 21 is in complete contact with the outer scissor foot shaft 122 and is engaged together. When the outer scissor foot shaft 122 slides into the hook part 21, the boss 121 simultaneously enters the hole 220.

[0033] 2. The inner scissor foot shaft overlaps the upper edge of the hook portion 210 at the other end of the support plate 200. Apply pressure to press the position of the inner scissor foot shaft, and the inner scissor foot shaft is inserted into the hook portion 210 to complete the assembly operation.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
