[0002] With the rapid development of information technology and the popularization of electronic devices, keyboards are an important tool for human-computer interaction, and their performance and design play a vital role in user experience and work efficiency. However, there are some obvious problems in the keyboard design in the prior art, especially in terms of key layout and noise control.

[0003] First, the key layout of existing keyboards is often too loose, and the spacing between keys is too large. Although this design can reduce the mutual interference between keys to a certain extent, it also causes users to accidentally touch adjacent keys when typing or performing other operations with fingers that are not long enough, thereby reducing the accuracy and efficiency of the operation. For users who need to use the keyboard frequently, the problem of accidental touches may seriously affect their work efficiency and experience. On the other hand, it will also increase manufacturing costs.

[0004] Secondly, the elastic parts of existing keyboard keys often generate noise when pressed. Such noise not only disturbs the user's working environment, but also may have adverse effects on the user's hearing and mental health. The keyboard noise problem is particularly prominent in places where quietness is required, such as libraries, offices, or when working at night.

[0005] Therefore, it is necessary to optimize the design of the keyboard keys in the prior art to solve the problems that the keys are not compact enough, the key spacing is large, and the key elastic parts are prone to generate noise. Utility Model Content

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] See also Figures 1 to 5A keyboard elastic silicone component comprises a silicone component body, on which a plurality of key positions are arranged, each of which is surrounded by an elastic wall 1, each of which comprises four straight-edge inclined walls 11 inclined inwardly, and a rounded-corner inclined wall 12 is provided at the connection between adjacent straight edges for transition, an angle a formed by the straight-edge inclined wall 11 and a horizontal plane is smaller than an angle b formed by the rounded-corner inclined wall 12 and a horizontal plane, and an angle b formed by the rounded-corner inclined wall 12 and a horizontal plane gradually increases from a side close to the straight-edge inclined wall to a part away from the straight-edge inclined wall; a groove 2 is provided on the silicone component body on the outer side of each elastic wall 1, and the groove 2 is used to fill a lubricating paste or a quick-drying oil film. The elastic wall 1 gradually changes from a smaller angle of the straight-edged inclined wall 11 to a larger angle of the rounded inclined wall 12, so that the radius of the elastic wall 1 at the rounded corner can be made smaller, which can reduce the size of the entire elastic wall 1, so that the keys can be arranged more compactly, and then the size of the entire silicone body can be reduced to reduce the material used and reduce production costs; and grooves for filling lubricating paste or quick-drying oil film are arranged around the elastic wall 1, which play a lubricating role in the process of key movement to reduce friction and thus achieve the effect of reducing noise. The straight-edged inclined wall 11 of the elastic wall 1 maintains the original angle size to maintain the original pressing feel as much as possible, and the angle of the rounded inclined wall 12 is increased as much as possible to help reduce the size of the arc, which can ensure the pressing feel and reduce the volume of the key at the same time. When installing keycaps on the keys, when the keycaps and silicone of the original keyboard move downward under force, the bottom of the keycap pressing column will stick to the upper surface of the silicone groove and have a sticky effect similar to a suction cup. At the same time, the inclined wall of the silicone protrudes about 0.2mm after being pressed, and will rub against the pressing column of the keycap to produce noise. When the key is released and moves upward, the bottom of the key pressing column and the silicone separate, which will produce a detachment noise. Therefore, this problem can be avoided by filling the groove with lubricating paste or quick-drying oil film.

[0024] See also Figures 1 to 5 Preferably, the angle a formed by the straight-edge inclined wall 11 and the horizontal plane is 40° to 70°; the angle b formed by the rounded inclined wall 12 and the horizontal plane is 40° to 70°. Preferably, a and b can be 40°, 45°, 60°, 69°, 70°, etc., but are not limited thereto. The closer the angle b is to 90°, the closer it is to the middle position. By increasing the angle of the rounded inclined wall 12 of the elastic wall 1, avoiding the keycap of the key can prevent the key from making noise and achieve a silent effect. The rounded inclined wall position of the silicone part avoids the keycap pressing column by shrinking the elastic inclined wall with a larger angle, so as to help reduce the radius of the arc, so that its rounded corner is farther away from the pressing column of the key, reducing the possibility of contact between the two, so as to achieve a silent effect.

[0025] See also Figures 1 to 5Preferably, waterproof ribs 3 are arranged around the periphery of the silicone body for waterproofing. The waterproof ribs 3 are arranged around the periphery of the silicone body, which can achieve a certain waterproof effect, reduce the possibility of liquid infiltration, effectively reduce the damage of the keyboard caused by water ingress, and help extend the service life.

[0026] See also Figures 1 to 3 Preferably, the waterproof rib 3 is provided with a plurality of notches 31, and the bottom surface of the notches 31 is higher than the upper surface of the silicone body. It is used to position the upper cover of the keyboard to prevent the silicone from moving, which may cause the waterproof rib straight wall gap and the rib gap of the upper cover to become large, thus causing waterproof failure.

[0027] See also Figures 1 to 5 Preferably, a groove 2 is provided at a position on the silicone body opposite to the rounded angled wall 12 of each elastic wall 1. Each corner of each elastic wall 1 can be lubricated to increase the lubrication effect and reduce the noise when the key is pressed. The noise is mainly generated by the friction at the rounded corner of the elastic wall 1. The key pressing mainly rubs the rounded corner of the elastic wall 1, so it is sufficient to lubricate this part.

[0028] See also Figure 1 to Figure 2 Preferably, the groove 2 at the position adjacent to the four rounded slanted walls 12 on the main body of the silicone part is circular; the groove 2 at the position adjacent to only two rounded slanted walls 12 on the main body of the silicone part is strip-shaped. The area of ​​the groove 2 adjacent to the four rounded slanted walls 12 is larger than the area of ​​the groove 2 adjacent to only two rounded slanted walls 12; the area of ​​the groove 2 adjacent to one rounded slanted wall 12 is smaller than the area of ​​the groove 2 adjacent to two rounded slanted walls 12. The groove 2 with more elastic walls 1 is designed to be larger in size so that it can store more lubricating paste or quick-drying oil film to meet the lubrication effect of more elastic walls 1, thereby achieving a better mute effect, that is, the inner groove 2 is larger, and the groove 2 arranged on the outer circle of the silicone part body is smaller, which can also play a role in reducing the overall size and reducing production costs.

[0029] See also Figures 1 to 4 Preferably, the outer edge of the silicone body is provided with a plurality of connecting ears 4 for inserting the connecting piece, so as to facilitate the assembly and fixation of the silicone body and the remaining components of the keyboard.

[0030] Preferably, the key sensitivity is adjusted by adjusting the wall thickness of the groove 2 on the silicone body. The thinner the wall thickness of the groove 2, the more sensitive the keyboard. Increasing the wall thickness at this location can reduce the keyboard sensitivity, while reducing the wall thickness can increase the keyboard sensitivity.

[0031] The utility model has the following working principle:

[0032] When the button is pressed during use, the button transmits force to the elastic wall 1, and the elastic wall 1 is deformed as a whole. Since the rounded angled wall 12 is limited by the two adjacent straight-edge inclined walls 11, it will push outward to contact the adjacent groove 2 and touch the lubricating paste or quick-drying oil film therein, and then the rounded angled wall 12 is covered with lubricating paste or quick-drying oil film, and the friction force of other parts touching the rounded angled wall 12 is significantly reduced, which can achieve a silent effect. In addition, the elastic wall 1 gradually changes from a smaller angle of the straight-edge inclined wall 11 to a larger angle at the position of the rounded angled wall 12, so that the radius of the elastic wall 1 at the rounded corner can be made smaller, which can reduce the size of the entire elastic wall 1, so that the button can be arranged more compactly, and then the size of the entire silicone body can be reduced to reduce the material used and reduce the production cost. Since the size of the rounded angled wall 12 is reduced, the deformation amount generated when pressing will also be reduced, which can avoid the transparent button and will not generate noise due to friction. Waterproof ribs 3 are arranged around the periphery of the silicone body, which can achieve a certain waterproof effect. The waterproof ribs 3 can block the entry of liquid in the surrounding area, reduce the possibility of liquid penetration, effectively reduce the damage of the keyboard caused by water ingress, and help extend the service life.
