[0019] Figure label: Housing 100, through hole 110, contact part 120, protrusion 121; Button 200. Detailed Implementation

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] In the description of this utility model, the use of terms such as first, second, third, fourth, and fifth is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0022] 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.

[0023] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. 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.

[0024] Reference Figure 1 and Figure 2 This utility model provides a button shaft, which includes a housing 100 and a button 200. The housing 100 has a through hole 110, and the button 200 is slidably inserted through the through hole 110. The housing 100 has a contact portion 120, wherein when the button 200 slides up or down relative to the housing 100, the contact portion 120 can abut against the button 200 to ensure that the tilt angle and lateral offset of the button 200 are within a preset range.

[0025] It is understandable that when the button 200 is subjected to axial force and slides vertically up and down, the button 200 and the contact part 120 do not come into contact (there is a gap between the two).

[0026] It is understood that the preset range for the tilt angle can be set to 0°~5° (inclusive); the preset range for the lateral offset can be set to 2mm~5mm (inclusive). Of course, the preset ranges for the tilt angle and the lateral offset can be set according to the user's actual needs.

[0027] With the above structure, a contact portion 120 is provided on the housing 100 for abutting against the button 200, which can provide effective lateral constraint for the up-and-down sliding of the button 200. This can effectively control the tilt and lateral displacement of the button 200 during movement (especially when subjected to non-axial force), and can ensure that the button 200 has a relatively vertical axial movement trajectory, thereby greatly improving the movement stability and guidance of the button 200.

[0028] In this embodiment, the material of the housing 100 is the same as that of the button 200, and the material of the button 200 is different from that of the contact portion 120.

[0029] Understandably, the housing 100 and button 200 can both be made of high-strength, impact-resistant polycarbonate (PC) material, while the contact part 120 can be made of polyoxymethylene (POM) material, which has an extremely low coefficient of friction and excellent wear resistance and self-lubricating properties.

[0030] It is understandable that when the button 200 slides up or down relative to the housing 100, the contact portion 120 can abut against the button 200, that is, the button 200 can slide and rub against the contact portion 120, so as to indirectly slide and rub against the housing 100.

[0031] With the above structure, on the one hand, since the housing 100 and the button 200 are made of the same material, when the button 200 is pressed and collides with the housing 100, the two generate concentrated vibration waves with similar vibration frequencies due to the same material, avoiding the scattered and noisy noise caused by the frequency difference of different materials, thus producing a crisp, consistent and concentrated knocking sound, significantly improving the user's high-quality auditory experience; on the other hand, by using a different material than the button 200 in the key part of sliding friction (contact part 120), when the button 200 and the housing 100 slide relative to each other, their contact interface is made of two materials with different coefficients of friction, effectively reducing the risk of adhesion and biting that easily occurs when the same material comes into contact, and ensuring the smoothness of the pressing feel.

[0032] It is understandable that the contact part 120 is smaller in size than the housing 100. Therefore, when the button 200 is pressed and collides with the housing 100, the dispersed vibration wave generated by the contact part 120 due to the different vibration frequency (small) has a small impact on the overall knock feedback sound and can be ignored.

[0033] In this embodiment, refer to Figure 1 and Figure 2 The contact portion 120 has a ring structure and is located on the top outer side of the housing 100. The point where the pressed button 200 collides with the housing 100 is located at the bottom of the housing 100. The button 200 can slide up and down through the contact portion 120.

[0034] With the above structure, the contact portion 120 is located on the top outer side of the housing 100, away from the collision point between the button 200 and the housing 100. Therefore, when the button 200 is pressed and collides with the housing 100, the vibration transmitted to the contact portion 120 is smaller, resulting in a smaller dispersed vibration wave generated by the contact portion 120. Thus, under this design, the effect of the dispersed vibration wave generated by the contact portion 120 on the overall tap feedback sound is negligible.

[0035] In some embodiments, the contact portion 120 may be disposed within the housing 100.

[0036] In this embodiment, the contact portion 120 is a different color from the housing 100.

[0037] Through the above structure, the two-color design can break the monotony of a single color, thereby increasing the product's sense of layering and design.

[0038] In this embodiment, refer to Figure 1 The inner ring of the contact portion 120 is provided with eight protrusions 121, which are evenly arranged around the axis of the contact portion 120. When the button 200 slides up or down relative to the housing 100, the contact portion 120 can abut against the button 200 through the corresponding protrusions 121.

[0039] In some embodiments, the number of protrusions 121 is set to six.

[0040] In some embodiments, the protrusions 121 evenly arranged along the axes of the eight annular through holes 110 are the contact portions 120.

[0041] In this embodiment, the contact portion 120 and the housing 100 are integrally formed. The contact portion 120 and the housing 100 can be integrally formed through a secondary injection molding process.

[0042] In some embodiments, the contact portion 120 and the housing 100 can be integrally formed by a hot melt welding process.

[0043] This invention also proposes a keyboard that includes the aforementioned key shaft. This structure improves the stability and directional accuracy of the buttons.

[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
