[0001] This technology belongs to the field of computer hardware, and particularly relates to an integrated audible and mute-switchable button spring optical axis key. Background Art

[0002] The optical axis key is a new type of key in recent years. It is based on the traditional mechanical key axis technology and incorporates a new optical induction recognition technology. By replacing the traditional contact dial with an optical induction component, some problems of the traditional contact mechanical switch are improved. The "optical axis" technology uses infrared optical induction. When conducting, there is no contact point and no wear. At the same time, the optical mechanical signal is an optical pulse, and the output waveform is clean and free of noise, completely eliminating the contact jitter problem. The key can respond super-fast within 1 ms when clicked.

[0003] The patent number of the prior art is: 201720816304.4, and the patent name is: A New Type of Dustproof and Waterproof Optical Axis Key. The method it adopts is a structure that makes sound through the mutual cooperation of the structural part on the guide core and the torsion spring. Due to different customer requirements, if the user needs mute operation, then this keyboard cannot be used. Summary of the Invention

[0004] Aiming at the deficiencies of the existing mechanical optical axis key functions, the technical problem solved by this new type is to provide an integrated audible and mute-switchable button spring optical axis key. A tuning switching device is added to the original design of the mechanical optical axis sound-generating key, which can arbitrarily switch the audible and mute functions in the same group of keys. The products of this technology have the characteristics of simplified process, simple structure, wide application range, and simple operation.

[0005] The integrated audible and mute-switchable button spring optical axis key includes: an upper cover, a guide core, a return spring, a sound-generating spring, a base, and a tuning guide post; and is characterized in that: a channel hole conforming to the outer contour of the upper end of the guide core is opened in the center of the upper cover, the upper end of the guide core is inserted into the channel hole of the upper cover from below, and the lower end of the guide core is sleeved with a return spring; the bottom of the return spring is limited by the internal structure of the base; a groove is provided on the side of the base, and a sound-generating spring is installed in the groove; a convex edge is provided on the side of the guide core. When the guide core moves downward, the convex edge of the guide core presses the sound-generating spring, and when the guide core bounces up, the sound-generating spring resets and hits the housing to make a sound; a guide adjustment hole is opened on one side of the upper cover, and a tuning guide post is installed in the guide adjustment hole; the tuning guide post guides and moves within the structure of the guide adjustment hole, changing the position change of the sound-generating spring, thereby completing the function of adjusting the sound of the optical axis key; the upper cover and the base are buckled with each other to form the optical axis key.

[0006] Preferably, the guiding and adjusting hole penetrates through the inside of the upper cover. On both sides of the middle part of the guiding and adjusting hole, there are raised inclined adjusting hole guiding grooves. In the middle of the adjusting hole guiding grooves of the guiding and adjusting hole, there is a limiting edge, which divides the guiding and adjusting hole into two limiting areas; the two limiting areas are respectively a sound generation control area and a mute control area; the inclined adjusting hole guiding grooves penetrate through the two limiting areas obliquely to achieve the effect of adjusting the height of the tuning guiding column.

[0007] Preferably, on both sides of the middle part of the tuning guiding column, there are concave and inclined tuning guiding grooves. After the tuning guiding column is inserted into the guiding and adjusting hole, the tuning guiding grooves cooperate with the adjusting hole guiding grooves to slide obliquely.

[0008] Preferably, the bottom end of the tuning guiding column is an inclined surface; the inclined surface at the bottom end of the tuning guiding column gradually moves downward to pry the position of the sound generation spring to move, so as to avoid the convex edge on the side of the guide core after descending, thereby avoiding making a sound.

[0009] Preferably, one or more first positioning devices are also provided on the tuning guiding column, and one or more second positioning devices are respectively provided in the two limiting areas in the guiding and adjusting hole. The structures of the first positioning device and the second positioning device are coupled with each other to achieve the effect of respectively assisting in positioning the tuning guiding column in the two limiting areas in the guiding and adjusting hole.

[0010] Preferably, the lower cover is connected to the keyboard substrate.

[0011] Preferably, the upper end of the guide core is connected to the keycap.

[0012] The integrated audible and mute switchable button spring optical axis key further includes an integrated audible and mute switchable button spring optical axis key adjustment method, and its usage method is as follows:

[0013] A. Sound generation adjustment method of the integrated key: The tuning guiding column is inserted into the key adjustment hole. Under the action of the limiting edge, the first positioning device and the second positioning device, the tuning guiding column stops in the first limiting area. At this time, the tuning guiding column is located at the upper end of the sound generation spring. When the key is used, the sound generation spring is used normally, and the sound generation spring can make a sound under the action of the guide core, that is, the sound generation effect of the key is realized.

[0014] B. Mute adjustment method of the integrated key: When the tuning guiding column is inserted into the key adjustment hole and under the action of external force, the tuning guiding column slides obliquely through the cooperation of the tuning guiding groove and the adjusting hole guiding groove and slides into the second limiting area in the adjusting hole. During the descending process, the inclined surface at the lower end of the tuning guiding column gradually pushes the position of the sound generation spring outwards. In this way, when the guide core is pressed down, the convex edge on the guide core will not be able to touch the sound generation spring either, thereby realizing the mute effect of the key.

[0023] Preferably, the guiding and adjusting hole 11 runs through the upper cover 1. On both sides of the middle part of the guiding and adjusting hole 11, there are raised inclined adjusting hole guiding grooves 111. In the middle of the adjusting hole guiding grooves 111 of the guiding and adjusting hole 11, there is a limiting edge 112, and the limiting edge 112 divides the guiding and adjusting hole 11 into two limiting areas; the two limiting areas are respectively a sound control area and a mute control area; the inclined adjusting hole guiding grooves 111 run through the two limiting areas obliquely to achieve the effect of adjusting the height of the tone-adjusting guiding column 6.

[0024] Preferably, on both sides of the middle part of the tone-adjusting guiding column 6, there are concave and inclined tone-adjusting guiding grooves 61. After the tone-adjusting guiding column 6 is inserted into the guiding and adjusting hole 11, the tone-adjusting guiding grooves 61 cooperate with the adjusting hole guiding grooves 111 to slide obliquely.

[0025] Preferably, the bottom end of the tone-adjusting guiding column 6 is an inclined surface 63; the inclined surface 63 at the bottom end of the tone-adjusting guiding column 6 moves downward gradually to pry the position of the sounding spring 4 to move, so as to avoid the convex edge 21 on the side of the guide core 2 after descending, thus avoiding making a sound.

[0026] Preferably, one or more first positioning devices 62 are further arranged on the tone-adjusting guiding column 6, and one or more second positioning devices 113 are respectively arranged in the two limiting areas in the guiding and adjusting hole 11.

[0029] The operation process of this technology is as follows:

[0030] In the original design of this key, after the guide core is pressed down to squeeze the sounding spring to deform, when it returns, the spring bounces against the housing to make a sound. The design principle of this design is to change the position of the sounding spring, so as to avoid the squeezing effect of the guide core pressing down on the sounding spring, making this key have a silent effect.

[0031] As Figure 5 shown, the sound adjustment method of the integrated key: The tone-adjusting guiding column 6 is inserted into the key adjusting hole 11. Under the action of the limiting edge 112, the first positioning device 61 and the second positioning device 113, the tone-adjusting guiding column 6 stops in the first limiting area. At this time, the tone-adjusting guiding column 6 is located above the sounding spring 4. When the key is used, the sounding spring 4 is used normally, and the sounding spring can make a sound under the action of the guide core, that is, the sound effect of the key is realized.

[0032] As Figure 6As shown in the figure, the method for adjusting the mute of the integrated button: The tuning guide post 6 is inserted into the button adjustment hole 11. Under the left and right external forces, the tuning guide post 6 slides obliquely in cooperation with the adjustment hole guide groove 111 through the tuning guide groove 61 and slides into the adjustment hole into the second limit area. During the descending process, the inclined surface 63 at the lower end of the tuning guide post 6 gradually pushes the position of the sounding spring 4 outwards. In this way, when the guide core is pressed down, the convex edge on the guide core will also not be able to touch the sounding spring, thus realizing the mute effect of the button.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
