Description

Technical Field

[0001] The present disclosure relates to the technical field of keyboard components, and in particular to a keyboard switch. Background Art

[0002] The mechanical axis is a key component of a mechanical keyboard. Its performance stability determines the service life of the keyboard, and its experience such as pressure, smoothness and sound feedback when pressing determines the input experience of the keyboard.

[0003] When the existing mechanical keyboard switch is pressed, the axis hits the bottom cover, thereby generating sound feedback. Long-term impact will cause damage to the bottom cover and the axis impact point, resulting in the need to replace the key switch as a whole. The repair cost is too high, and because the materials of the bottom cover and the axis are fixed and cannot be replaced, the sound feedback effect of the key cannot be changed.

DETAILED DESCRIPTION

[0023] The technical solution of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0024] Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present disclosure.

[0025] In the description of the present disclosure, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present disclosure. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0027] Example

[0028] like Figure 1-4 As shown, this embodiment provides a keyboard switch, including a bottom cover 2, an upper cover 1 and an axis 3, the bottom cover 2 and the upper cover 1 are clamped and fixed by a snap structure, the axis 3 is embedded in the upper cover 1 and the bottom cover 2, a push rod assembly 31 is provided at the bottom of the axis 3, a guide groove 21 is provided at a position of the bottom cover 2 corresponding to the push rod assembly 31, the push rod assembly 31 is inserted into the guide groove 21, an opening is provided at the bottom of the guide groove 21, and an impact member 4 is detachably connected to the opening of the guide groove 21, by pressing the axis 3, the push rod assembly 31 moves downward and collides with the impact member 4, thereby generating sound feedback while triggering the key.

[0029] Specifically, the impact member 4 includes an integrally formed impact portion 41 and a mounting portion 42, the cross-sections of the impact portion 41 and the mounting portion 42 are "T"-shaped structures, and the opening at the bottom of the guide hole becomes narrower toward the outside, so that the mounting portion 42 can pass through the opening at the bottom of the guide hole while the impact portion 41 cannot, thereby preventing the impact member 4 from falling off.

[0030] Among them, the installation must be provided with an undercut 43 at the bottom, the undercut 43 is made of a deformable material, and chamfers are provided around the undercut 43. The chamfer setting enables the undercut 43 to smoothly pass through the opening at the bottom of the guide hole. When the push switch is inverted, the undercut 43 can prevent the impact member 4 from falling into the guide hole.

[0031] Specifically, the push rod assembly 31 includes a push rod body 311 integrally formed with the bottom of the axis 3, the push rod body 311 is a cylindrical structure with a hollow interior and an open bottom, and an external thread is provided on the outer side of the bottom of the push rod body 311, and the bottom of the push rod body 311 is detachably connected to a limiting cover 312, and the limiting cover 312 is provided with an internal thread, which cooperates with the external thread of the push rod body 311, and an installation groove 314 is provided inside the push rod body 311, and a knocking block 313 is embedded in the installation groove 314, and one end of the knocking block 313 passes through the limiting cover 312. When replacing the knocking block 313, it only needs to unscrew the limiting cover 312 to replace it, which is simple and quick.

[0032] Furthermore, a spring block is integrally formed on the side of the knocking block 313, and a first spring 315 is embedded in the mounting groove 314. One end of the first spring 315 is clamped on the spring block, and the other end is set against the inner wall of the mounting groove 314. The knocking block 313 is pushed out of the limiting cover 312 by the first spring 315, and plays a certain buffering role when the knocking block 313 and the impact part 41 collide with each other, thereby improving the service life of the knocking block 313 and the impact part 41.

[0033] Furthermore, a second spring 5 is sleeved on the outer side of the push rod assembly 31, and the two ends of the second spring 5 are respectively set against the shaft 3 and the bottom cover 2. When the shaft 3 is struck, the shaft 3 moves to drive the second spring 5 to compress, and when the shaft 3 is released, the second spring 5 drives the shaft 3 to reset, thereby playing a reset role.

[0034] Specifically, guide bars 32 are integrally formed on both sides of the axis 3, and guide grooves 22 are provided at positions of the bottom cover 2 corresponding to the guide bars 32, and the guide bars 32 are slidably connected in the guide grooves 22. The guide grooves 22 guide the moving direction of the guide bars 32 to ensure that the moving direction of the axis 3 is accurate, avoiding deviation and causing jamming during the up and down movement of the axis 3.

[0035] Furthermore, a plurality of rotating members 321 are rotatably connected to both sides of the guide bar 32, and the rotating members 321 are disposed against the inner wall of the guide groove 22. The rotating members 321 may be pulleys or balls, etc., and the rotating members 321 roll on the inner wall of the guide groove 22, thereby reducing the contact area between the guide bar 32 and the guide groove 22, reducing friction, improving the smoothness of movement, reducing the noise generated by friction, and improving the sound feedback effect.

[0036] Furthermore, the impact member 4 and the knocking block 313 are made of one of metal, rubber and plastic. In this embodiment, the sound produced by the impact member 4 and the knocking block 313 after the collision can be changed by changing the material of the impact member 4 and the knocking block 313, so that the sound feedback can be changed according to the demand by changing the material.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
