Specifically, the key switch in this embodiment mainly comprises a base 100, a rubber cover 300, a button 400, a terminal assembly 700 and a spring 600, wherein a hollow column 110 and a mounting groove 120 are arranged on the base 100, the terminal assembly 700 is arranged in the mounting groove 120, the rubber cover 300 and the base 100 are fastened together to form an inner cavity, the button 400 and the spring 600 are respectively arranged in the inner cavity, one end of the button 400 is provided with a guide column 410 which is inserted into the hollow column 110 to slide, the other end of the button 400 penetrates through the top of the rubber cover 300 to extend outwards, the spring 600 is sleeved on the hollow column 110, two ends of the spring 600 respectively abut against the button 400 and the base 100, when the button 400 is pressed downwards, the guide column 410 slides downwards in the hollow column 110, and the pressing wall of the button 400 touches the terminal assembly 700, so as to realize signal switching.
In order to achieve the noise reduction and silencing effect when the keyboard is pressed and rebounded, the soft rubber pad 200 is arranged at the bottom in the hollow column 110, and when the pressing part 400 presses downwards, the soft rubber pad 200 can avoid the direct collision between the guide column 410 and the bottom in the hollow column 110, so that the noise reduction and silencing effect can be buffered when the keyboard is pressed; and when reseing through spring 600 according to sincere 400, through according to the buffer structure 500 of sincere 400 side and the inboard butt department in jiao gai 300 top, make according to sincere 400 when kick-backing and form the sliding friction buffering contact principle between the jiao gai 300, avoid with this according to sincere 400 and the direct collision of jiao gai 300, reach the silence effect of making an uproar equally, finally, make the keyboard press downwards and when upwards kick-backing, all can realize making an uproar silence of making an uproar.
In order to better realize the noise reduction function, the soft rubber pad 200 is arranged at the bottom in the hollow column 110 in an interference or bonding mode, so that the soft rubber pad 200 can be conveniently installed, meanwhile, the soft rubber pad 200 is made of silica gel, PVC, polyamide elastomer, polyolefin elastomer or polyurethane elastomer, and the soft rubber pad has the characteristics of high impact resistance, easiness in processing, reusability and the like, so that the key switch can achieve a mute effect better, and meanwhile, the service life of the key switch of the keyboard can be prolonged.
Referring to fig. 2, 3 and 4, in order to make the design of the buffer structure reasonable, the buffer structure 500 includes a buffer groove 510 and a buffer block 520, the buffer groove 510 is disposed at the side of the pressing unit 400, the buffer block 520 is disposed at the inner side of the top of the rubber cover 300, wherein both sides of the buffer groove 510 and both sides of the buffer block 520 are designed as inclined planes.
In this embodiment, the shape of the buffering groove 510 is the same as that of the buffering block 520, the angle of the inclined plane formed between the two sides of the buffering groove 510 is smaller than that formed between the two sides of the buffering block 520, and meanwhile, the inclined planes of the buffering groove 510 and the buffering block 520 are matched with each other, so as to achieve the buffering mute effect.
After the pressing pad 400 is released, the pressing pad 400 rebounds and resets under the elastic force of the spring 600, and when the pressing pad 400 resets upwards, the buffer groove 510 at the side of the pressing pad 400 moves towards the direction of the buffer block 520 at the inner side of the top of the rubber cover 300, because the angle of the inclined plane formed between the two sides of the buffer block 520 is larger than the angle of the inclined plane formed between the two sides of the buffer groove 510, when the buffer block 520 is inserted into the buffer groove 510, the buffer groove 510 is expanded, and simultaneously, due to the elastic buffering of the buffer groove 510, the friction force between the side wall of the buffer block 520 and the side wall of the buffer groove 510 is increased, so as to achieve the buffering effect, finally, the side edge of the pressing pad 400 is prevented from directly colliding with the inner side of the top of the rubber cover 300, the noise reduction and silencing effects are realized, and the buffer groove 510 at the side edge of the pressing pad 400 is limited by the buffer block 520 at the inner side of the top of the rubber cover 300, so that when the pressing pad 400 rebounds is prevented, directly separated from the rubber cover 300, so that the design of the buffer structure is reasonable.
Example two:
the key switch in this embodiment is basically the same as the key switch in the first embodiment, and the main differences are as follows: the buffer groove 510 is disposed on the inner side of the top of the rubber cover 300, and the buffer block 520 is disposed on the side of the pressing unit 400.
Similarly, after the pressing pad 400 is released, the pressing pad 400 performs rebound resetting under the elastic force of the spring 600, and when the pressing pad 400 resets upwards, the buffer block 520 at the side of the pressing pad 400 moves towards the buffer groove 510 at the inner side of the top of the rubber cover 300, because the angle of the inclined plane formed between the two sides of the buffer block 520 is larger than the angle of the inclined plane formed between the two sides of the buffer groove 510, when the buffer block 520 is inserted into the buffer groove 510, the buffer groove 510 is opened, and simultaneously, due to the elastic buffering of the buffer groove 510, the friction force between the side wall of the buffer block 520 and the side wall of the buffer groove 510 is increased, so as to achieve the buffering effect, finally, the side edge of the pressing pad 400 is prevented from directly colliding with the inner side of the top of the rubber cover 300, thereby realizing the noise reduction and silence effects, and the buffer groove 510 at the inner side of the top of the rubber cover 300 limits the buffer block 520 at the side edge of the pressing pad 400, thereby preventing the pressing pad 400 from rebounding, directly separated from the rubber cover 300, thereby making the design of the buffering structure reasonable.
The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. The present invention may be readily implemented by those skilled in the art as illustrated in the accompanying drawings and described above; however, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the scope of the utility model as defined by the appended claims; meanwhile, any changes, modifications, and evolutions of the equivalent changes of the above embodiments according to the actual techniques of the present invention are still within the protection scope of the technical solution of the present invention.
