The specific meaning of the above terms in the present utility model can be understood as appropriate by those of ordinary skill in the art.

The technical scheme of the utility model is specifically described below with reference to the accompanying drawings.

The utility model provides a keyboard switch with a special structure, which comprises a button 1 and a base 2. Compared with the traditional keyboard switch, the button 1 has a cylindrical structure, the peripheral side wall of the button is outwards protruded to form a limit convex column 11, as shown in fig. 1, and the upper surface of the base 2 is protruded and forms a limit baffle 21 matched with the limit convex column 11, as shown in fig. 2. When the button 1 is mounted on the base 2 according to design requirements, the limit baffle 21 can limit the button 1 to rotate along the circumferential direction without affecting the axial movement of the button 1.

The limit baffle 21 can prevent the button 1 from rotating circumferentially towards a certain direction relative to the base 2 in a manner of being mutually matched with the limit convex column 11, so that the problem that the cylindrical key shaft is easy to rotate in use is solved to a certain extent.

As an alternative embodiment, two opposite sides of the button 1 are outwardly convex and form a boss 12, and at least one limiting boss 11 is arranged between the two bosses 12.

The limiting convex columns 11 are arranged between the two bosses 12, and the effective limiting of the limiting convex columns 11 can be realized by further matching with the bosses 12, so that the rotation of the limiting convex columns 11 is avoided.

As an alternative embodiment, the upper surface of the base 2 is also formed with a guide groove 22 that cooperates with the boss 12; when the button 1 is inserted into the base 2 through the guide groove 22, the limit stud 11 can be just connected with or adjacent to the limit baffle 21.

When the limiting convex column 11 is just connected with the limiting baffle plate 21, the limiting baffle plate 21 can directly prevent the button 1 with the limiting convex column 11 from rotating towards a certain direction when the limiting convex column 11 and the limiting baffle plate 21 are in direct contact; when the limit stud 11 is adjacent to the limit stop 21, a gap is present between them and the size of this gap is small (only to avoid direct friction between them affecting the normal use of the push button 1). The size of the gap is so small that the button 1 can only undergo a slight deflection relative to the limit stop 21 that is not visible to the naked eye.

In order to reduce the influence of the limit stop 21 on the button 1 as much as possible, the side walls of the limit stop 21 opposite to the limit posts 11 are smooth or even.

As an alternative embodiment, the number of the limit posts 11 is even and symmetrically distributed outside the button 1, as shown in fig. 1.

In this embodiment, the number of the limiting posts 11 is four, and two limiting posts 11 are disposed between two adjacent bosses 12.

The symmetrically arranged limit stud 11 means that the limit stop 21 is also symmetrically arranged, as shown in fig. 2, so that circumferential limitation of the push button 1 can be achieved in two different directions.

As an alternative embodiment, the limit stop 21 is a sheet-like or L-shaped structure.

In this embodiment, as shown in fig. 2, the limit stop 21 has a substantially L-shaped structure with a certain angle. When the button 1 is positioned on the base 2, the limit stud 11 is positioned between the limit stop 21 and the guide groove 22.

As an alternative embodiment, the outer sidewall of the boss 12 is sleeved with the buffer member 13 and the upper surface and/or the lower surface of the buffer member 13 is outwardly protruded with respect to the boss 12, as shown in fig. 1.

Because the buffer piece 13 can be raised relative to the upper surface and/or the lower surface of the boss 12, in the process that the button 1 moves up and down under external pressure, the buffer piece 13 can be contacted with a related structure above or below the boss 12 before the boss 12, so that the boss 12 is prevented from being directly contacted with and colliding with the related structure, the sound generated by the key in use is greatly reduced, and because the buffer piece 13 has better buffer effect, the sound generated when the buffer piece 13 is contacted with the corresponding structure surface can be effectively reduced or even avoided, thereby achieving the purpose of reducing the working noise of the keyboard and enabling the key to be quieter in use; in addition, this structure may also help to extend the service life of the key by reducing the likelihood and strength of contact and impact of boss 12 with the associated structure.

As an alternative embodiment, the buffer 13 is a hollow annular structure; and/or, an annular groove 121 is formed on the outer circumferential side wall of the boss 12, and the buffer member 13 is connected to the boss 12 via the annular groove 121, as shown in fig. 3.

The buffer piece 13 is of an annular or ring-like structure, can be connected with the boss 12 in a sleeved mode, can effectively reduce the mounting difficulty of the buffer piece 13, and improves the assembly efficiency of the button 1 and the buffer piece 13. The annular groove 121 can help to fix the buffer piece 13, so that the buffer piece 13 and the boss 12 are combined more firmly, the mounting difficulty of the buffer piece 13 is reduced, and the assembly efficiency of the button 1 and the buffer piece 13 is improved.

It should be noted that the buffer member 13 is made of a material having good elasticity, capable of being slightly deformed and capable of being rapidly deformed, such as a silicone rubber or a rubber material. In addition, the shape and size of the internal hollow structure of the buffer member 13 need to match the structure of the annular groove 121 on the boss 12, so as to avoid shaking of the buffer member 13 relative to the boss 12.

In order to facilitate the installation and ensure the buffer member 13 to have a better mute buffer effect, the inner peripheral side wall of the buffer member 13 is provided with a curved surface with larger curvature, such as an arc, so as to reduce the friction force in the installation process of the buffer member 13; accordingly, the peripheral side wall of the buffer member 13 is formed of a flat or approximately flat curved surface, thereby ensuring that the buffer member 13 can better exert its silencing and buffering effects.

The buffer member 13 having the above-described configuration also has the advantage of convenient processing and convenient installation.

The key also comprises an upper cover 3, a spring and other structures, as shown in fig. 3, in the process of up-and-down movement of the button 1, the boss 12 can drive the buffer element 13 to move up and down along with the up-and-down movement, and at this time, the buffer element 13 can be contacted with the upper cover 3 or the base 2 so as to realize a mute buffer effect. The structures of the upper cover 3, the springs, and the like are all the prior art.

In order to better limit the button 1, in this embodiment, the lower surface of the upper cover 3 is recessed inward and a limit groove 31 capable of being matched with the limit post 11 is formed, as shown in fig. 3.

When the upper cover 3 and the lower cover are buckled to form a cavity for accommodating the button 1, the button 1 positioned in the cavity can move up and down under the action of external force, and the limit convex column 11 can approach or depart from the limit groove 31 at the moment, so that the limit baffle 21 is matched to further limit the limit convex column 11.

As an alternative embodiment, the light guide post 4 is further included, and at least one axial side wall of the light guide post 4 is partially protruded and forms a positioning buckle 41, as shown in fig. 6; the upper surface portion of the base 2 is recessed and formed with a through groove 23 for mounting the light guide column 4, and a positioning groove 231 matched with the positioning buckle 41 is formed on the side wall of the through groove 23, as shown in fig. 2; the light guide column 4 can be fixedly mounted on the base 2 through the positioning groove 231.

The above-mentioned mutually supporting location buckle 41 and the positioning groove 231 can realize the quick installation to the leaded light post 4, and simple structure is convenient.

It should be noted that when the base 2 is a transparent structure, the light guide column 4 may be first mounted on the base 2, and then the upper cover 3 may be fastened on the base 2; when the base 2 is of an opaque structure, in order to achieve a better light guiding effect, a hole through which the light guiding column 4 can pass is formed at a position of the upper cover 3 corresponding to the through groove 23, as shown in fig. 4 and 5, and the light guiding column 4 is mounted on the base 2 through the upper cover 3.

In this embodiment, since the light guide column 4 is partially disposed outside the upper cover 3, the keyboard switch can be designed to be shorter to a certain extent so as to have a lower height.

The utility model also provides a keyboard, which comprises the keyboard switch with the special structure.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
