[0020] Example: A magnetic shaft key 40 for a keyboard includes a key mounting base 1, a key cover 2, a pressing shaft 3, a spring 4, and a magnet 5. The key mounting base 1 has a body clip 11 for mounting onto the keyboard body. The lower end of the key mounting base 1 also has a mounting positioning post 12 that can be inserted into a positioning hole on the circuit board 20 of the keyboard. The key cover 2 is fixedly mounted on the upper end of the key mounting base 1 by the clip. The key cover 2 and the key mounting base 1 together form a movable cavity for the pressing shaft 3. The inner bottom surface of the key mounting base 1 also has a guide sleeve 13. The pressing shaft 3 is circumferentially stopped and axially slidable, inserted into the movable cavity of the pressing shaft 3. The upper end of the pressing shaft 3 has a cross-shaped insertion post 31 that can extend a set distance beyond the upper end of the key cover 2. At least two opposite outer side walls of the pressing shaft 3 also have protruding limiting blocks 32. The key cover... The inner wall of the button cover 2 is provided with a guide limiting groove 21 that is directly opposite to the protruding limiting block 32. The guide limiting groove 21 has a structure with an open bottom and a closed top. The protruding limiting block 32 on the pressing shaft 3 is slidably inserted into the guide limiting groove 21 on the inner wall of the button cover 2. The upper end of the protruding limiting block 32 stops on the closed step surface at the upper end of the guide limiting groove 21. The lower end of the pressing shaft 3 is provided with a guide post 33. The guide post 33 is slidably inserted into the guide sleeve 13 on the bottom surface of the button mounting base 1. The lower end of the guide post 33 of the pressing shaft 3 is provided with a magnet 5 embedding groove. The magnet 5 is fixedly embedded in the magnet 5 embedding groove. The spring 4 is sleeved on the outer circumference of the guide post 33. The upper end of the spring 4 is tightly pressed against the step surface formed between the guide post 33 and the lower end of the pressing shaft 3. The lower end of the spring 4 is tightly pressed against the inner bottom surface of the button mounting base.

[0021] The pressing shaft 3 is fixed with protruding limiting blocks 32 on both sides. The inner wall of the button cover 2 has upper guide limiting grooves 21 on both sides. The protruding limiting blocks 32 slide inside the guide limiting grooves 21. The top of the inner wall of the guide limiting groove 21 limits the movement of the protruding limiting blocks 32, preventing the pressing shaft 3 from dislodging from the mounting position. At the same time, the guide post 33 at the lower end of the pressing shaft 3 slides relative to the guide sleeve 13 of the button mounting base 1, and the double guidance ensures the sliding accuracy of the pressing shaft 3.

[0022] The pressing shaft 3 is surrounded by a square frame 34. The cross-shaped insertion post 31 at the upper end of the pressing shaft 3 and the guide post 33 at the lower end of the pressing shaft 3 are both located inside the outer frame 34. Each of the four corners of the outer frame 34 has a protruding arc-shaped guide post 35. The inner side of the button cover 2 has a square hole 22 that matches the outer frame 34 of the pressing shaft 3. Each of the four corners of the square hole 22 has an arc-shaped guide groove 23 that matches the arc-shaped guide post 35 on the pressing shaft 3. The outer frame 34 and the arc-shaped guide posts 35 are inserted into the square hole 22 and the arc-shaped guide groove 23 of the button cover 2. When the pressing shaft 3 slides up and down, it is further guided by the arc-shaped guide post 35 and the arc-shaped guide groove 23, further improving the guiding accuracy of the pressing shaft 3.

[0023] An elastic buffer pad 36 is fixedly attached to the lower end of the outer frame 34 of the pressing shaft 3. A silent contact surface 14, directly opposite the outer frame 34 of the pressing shaft 3, is provided on the inner bottom surface of the button mounting base 1 at the location of the guide sleeve 13. The elastic buffer pad 36 at the lower end of the outer frame 34 of the pressing shaft 3 contacts the silent contact surface 14, limiting the descent distance of the pressing shaft 3. After the pressing shaft 3 slides to its final position, it contacts the silent contact surface 14 on the inner bottom surface of the button mounting base 1 via the elastic buffer pad 36, achieving a silent effect.

[0024] A rigid slider 15 is provided inside the guide sleeve 13 on the inner side of the button mounting base 1, which can slide up and down a set distance. When the rigid slider 15 is in the high position, during the downward sliding of the pressing shaft 3, the lower end face of the guide post 33 at its lower end contacts the rigid slider 15 before the elastic buffer pad 36 contacts the silent contact surface 14. When the rigid slider 15 is in the low position, during the downward sliding of the pressing shaft 3, the elastic buffer pad 36 at the lower end of the outer frame 34 contacts the silent contact surface 14 before the guide post 33 contacts the rigid slider 15. The outer wall of the button mounting base 1 is provided with a rigid slider 15 position adjustment and positioning device, which can adjust the rigid slider 15 to a high or low position and fix the adjusted rigid slider 15 in a fixed position.

[0025] By operating the position adjustment and positioning device of the rigid slider 15, the rigid slider 15 slides upward, causing the guide post 33 at the lower end of the pressing shaft 3 to first contact the rigid slider, resulting in a noticeable impact sound. By operating the position adjustment and positioning device of the rigid slider 15 in the opposite direction, the rigid slider 15 slides downward, causing the elastic buffer pad 36 at the lower end of the pressing shaft 3 to contact the silent contact surface 14, achieving a silent effect. This structure enables the selection of keyboard key silence and keystroke sound, and is suitable for various environments to meet the needs of different users.

[0026] The rigid slider 15 position adjustment and positioning device is a push-pull slider 16 that can be horizontally slidably mounted on the bottom outer side of the button mounting base 1. The upper end of the push-pull slider 16 contacts the lower end of the rigid slider 15 via an inclined surface. The bottom outer side of the button mounting base 1 has two recesses spaced apart along the sliding direction of the push-pull slider 16. A protrusion is fixedly provided on the push-pull slider. When the push-pull slider 16 slides to its two extreme positions, the protrusion can be inserted into one of the recesses to stop and position the push-pull slider 16. Sliding the push-pull slider 16 left and right via the inclined surface allows the rigid slider 15 to move up and down, thereby changing its height position.

[0027] The bottom outer side of the button mounting base 1 is also provided with a push-pull slide 16 guide slide, and the push-pull slide 16 can be accommodated in the push-pull slide 16 guide slide at a set distance.

[0028] The key cover 2 is fixedly installed on the upper end of the key mounting base 1 by a snap fastener as follows: the key mounting base 1 has several vertically extending openings on at least two opposite outer side walls. The bottom surface of the openings has an inverted first protrusion 17. The lower end face of the key cover 2 stops on the upper end face of the key mounting base 1. Several cantilevered elastic arms 24 extend downward from the lower end face of at least two opposite side walls of the key cover 2. The cantilevered elastic arms 24 can be inserted into the openings on the side walls of the key mounting base 1 one by one. The free ends of the cantilevered elastic arms 24 have inverted second protrusions 25 on both the inner and outer sides. The second protrusion 25 on the inner side of the cantilevered elastic arm 24 is fastened to the first protrusion 17. The second protrusion 25 on the outer side of the cantilevered elastic arm 24 can be fastened to the side wall of the key mounting slot 301 on the keyboard body. The key cover 2 is connected to the key mounting base 1 by the second protrusion 25 on the inner side of the cantilever elastic arm 24 at the lower end of the key cover 2. At the same time, the second protrusion 25 on the outer side of the cantilever elastic arm 24 is used to fix and position the magnetic axis key 40 on the keyboard body. The structure is simple and the fixation is stable.

[0029] A magnetic axis keyboard includes a keyboard housing 10, a circuit board 20, a positioning plate 30, magnetic axis keys 40, and keycaps 50. The positioning plate 30 and the circuit board 20 are fixedly installed inside the keyboard housing 10 from top to bottom. The circuit board 20 has a plurality of positioning holes for the magnetic axis keys 40 to be inserted and positioned by mounting positioning posts 12. The positioning plate 30 has a plurality of key mounting slots 301 corresponding to the positions of each magnetic axis key 40. The key mounting base 1 of the magnetic axis key 40 can be inserted into the key mounting slot 301, and the key of the magnetic axis key 40 is... The main body buckle 11 on the outer side wall of the key mounting base 1 and the second protrusion 25 on the outer side of the cantilever elastic arm 24 of the key cover 2 can be fastened to the lower side of the positioning plate 30 to achieve the fastening and positioning of the magnetic shaft key 40. The control circuit of the circuit board 20 is provided with several magnetic force sensors 201 corresponding to each magnetic shaft key 40. The magnetic force sensor 201 can sense the height position of the magnet 5 on the magnetic shaft key 40. The keycap 50 is detachably fixedly installed on the upper end of the pressing shaft 3 of the magnetic shaft key 40. Different keycaps 50 are provided with key markings.

[0030] The magnetic sensor 201 is a Hall element. When the button is pressed, the relative position of the magnet 5 and the Hall element changes, generating an electrical signal, thereby achieving magnetic triggering.
