DETAILED DESCRIPTION

[0020] In this embodiment, the present invention includes a main body and a plurality of keyboard switches 1 that are pluggable and arranged on the main body. The keyboard switch 1 includes a key seat 10, a key core 11, a reset straight spring 12, a spring limiting plate 13 and a conical induction spring 14. The key core 11 is slidably fitted in the key seat 10, and the spring limiting plate 13 is limitedly fitted with the key seat 10. A notch is provided at the diagonal portion of the bottom surface of the spring limiting plate 13, and the notch and the key seat 10 form a silencer hole 9. The reset straight spring 12 is arranged between the key core 11 and the spring limiting plate 13, and the two ends of the reset straight spring 12 are respectively limitedly fitted with the lower end of the key core 11 and the upper end of the spring limiting plate 13, and the conical induction spring 14 is limitedly fitted on the bottom surface of the spring limiting plate 13. It can be seen that the key base 10 supports and limits the key core 11 and the spring limiting plate 13, the key core 11 limits the upper end of the reset straight spring 12, and the spring limiting plate 13 supports and limits the lower end of the reset straight spring 12. The key core 11 slides in the key base 10 to press the reset straight spring 12, and the reset straight spring 12 resets the key core 11 when it is pressed. The silencer hole 9 prevents the key core 11 from directly hitting the spring limiting plate 13 when it is pressed, thereby silencing the key core 11.

[0021] In this embodiment, the keyboard structure also includes a fixed plate 2, a sealed waterproof silicone pad 3 and a PCB board 4. The fixed plate 2 is provided with a plurality of limit holes 20, and a plurality of keyboard switches 1 are limitedly matched on the limit holes 20. The fixed plate 2 and the PCB board 4 are respectively limitedly matched at the upper and lower ends of the sealed waterproof silicone pad 3. The sealed waterproof silicone pad 3 is provided with a plurality of sensing holes 30. The keyboard switch 1 is limitedly matched with the sealed waterproof silicone pad 3. The conical sensing spring 14 is limitedly matched at the bottom of the keyboard switch 1. The conical sensing spring 14 passes through the sensing hole 30 and is inductively matched with the PCB board 4. It can be seen that the keyboard switch 1 plays a role in pressing the conical induction spring 14, so that the shape of the conical induction spring 14 changes, thereby changing the capacitance of the conical induction spring 14 on the PCB board 4, thereby indirectly realizing the output of the keyboard signal and the on and off of the keyboard switch. The fixed plate 2 plays a role in connecting and cooperating with the sealing waterproof silicone pad 3 and the PCB board 4, thereby playing a sealing role and realizing the waterproof and dustproof effect to a certain extent. The limiting hole 20 plays a role in limiting the keyboard switch 1 on the fixed plate 2. The sealing waterproof silicone pad 3 plays a role in waterproofing, dustproofing and silencing the keyboard structure. The PCB board 4 plays a role in sensing the changes in the capacitance and speed of the conical induction spring 14 and transmitting the signal.

[0022] In this embodiment, the spring limiting plate 13 is provided with a spring limiting column 130 and a conical spring limiting hole 131 at the upper and lower ends respectively, the return straight spring 12 and the conical induction spring 14 are respectively limited and matched with the spring limiting column 130 and the conical spring limiting hole 131, and the spring limiting plate 13 is provided with a limiting tooth 132 at the left and right ends respectively, and the limiting tooth 132 is limited and matched with the internal part of the key seat 10. It can be seen that the spring limiting plate 13 supports and limits the spring limiting column 130, the cone spring limiting hole 131 and the pair of limiting teeth 132. The spring limiting column 130 and the cone spring limiting hole 131 respectively limit the return straight spring 12 and the cone sensing spring 14. The limiting teeth 132 limit the spring limiting plate 13 to the key base 10, so that the spring limiting plate 13 is firmly limited and fixed in the key base 10. The two guide columns 110 of the key core 11 pass through the silencer hole 9 and contact and cooperate with the press-down silencer silicone convex pad 32, so that the silencer effect is achieved when pressed, and at the same time, the guide column 110 is prevented from directly hitting the PCB board 4 to cause damage to the circuit on the PCB board 4. The silencer hole 9 and the press-down silencer silicone convex pad 32 can form a closed environment, which plays a waterproof role and delays the use time of the keyboard.

[0023] In this embodiment, a pair of vertical guide grooves 100 are provided at the top corners of the key base 10, and ear buckles 101 are provided on both sides of the key base 10. The key base 10 is limitedly matched with the fixing plate 2 through the pair of ear buckles 101. It can be seen that the key base 10 supports and fixes the pair of vertical guide grooves 100 and the pair of ear buckles 101, and the vertical guide grooves 100 guide the guide column 110 on the key core 11, so that the key core 11 slides up and down in the key base 10, and the pair of ear buckles 101 limit the key base 10 on the fixing plate 2.

[0024] In this embodiment, the fixing plate 2 is further provided with a connecting column 21, and the sealing and waterproof silicone pad 3 and the PCB board 4 are provided with connecting holes that slide with the connecting column 21, and the connecting holes of the sealing and waterproof silicone pad 3 and the PCB board 4 slide with the connecting column 21 in turn, and the connecting column 21 is limitedly matched with the screw 5. It can be seen that the fixing plate 2 supports and fixes the connecting column 21, and the connecting column 21 limits and connects the sealing and waterproof silicone pad 3 and the PCB board 4, so that the fixing plate 2, the sealing and waterproof silicone pad 3 and the PCB board 4 are firmly limitedly matched with each other.

[0025] In this embodiment, a plurality of electrostatic capacitance sensing areas 40 are arranged on the PCB board 4, and a RBG lamp 41 is arranged next to the electrostatic capacitance sensing area 40. It can be seen that the PCB board 4 supports and fixes the RBG lamp 41, and the electrostatic capacitance sensing area 40 is aligned with the sensing hole 30 on the sealing waterproof silicone pad 3. The electrostatic capacitance sensing area 40 senses the change of capacitance and transmits the signal to the PCB board 4, thereby realizing the on and off of the electrostatic capacitance keyboard switch.

[0026] In this embodiment, two opposing guide posts 110 are provided at the bottom of the key core 11, and the key core 11 slides with the vertical guide groove 100 through the guide posts 110. A release-silencing silicone ring 111 is provided near the top of the guide posts 110, and the release-silencing silicone ring 111 contacts and cooperates with the inner wall of the key base 10. It can be seen that the key core 11 supports and limits the pair of guide posts 110 and the release-silencing silicone ring 111, and the guide posts 110 guide the key core 11 to slide along the vertical guide groove 100 on the key base 10, and the release-silencing silicone ring 111 prevents the top surface of the pair of guide posts 110 from hard contacting with the top of the inner wall of the key base 10 when the key core 11 is reset, thereby playing a role of silencing.

[0027] In this embodiment, the sealing waterproof silicone pad 3 is provided with a sealing waterproof silicone boss 31, and two diagonal push-down silencer silicone convex pads 32 are provided on the sealing waterproof silicone boss 31. Waterproof silicone walls 33 are provided around the sealing waterproof silicone boss 31, and two adjacent waterproof silicone walls 33 are connected and matched. The push-down silencer silicone convex pad 32 contacts and matches with the silencer hole 9 and the guide column 110 in turn. It can be seen that the sealing waterproof silicone pad 3 supports and fixes the sealing waterproof silicone boss 31, the push-down silencer silicone convex pad 32 and the waterproof silicone wall 33, and the sealing waterproof silicone boss 31 serves as a limit fit for the keyboard switch 1 on the sealing waterproof silicone pad 3, and the push-down silencer silicone convex pad 32 contacts and matches with the guide column 110 to silence the sound, and the waterproof silicone wall 33 cooperates with the keyboard switch 1 to be waterproof and dustproof.

[0028] In this embodiment, the sealing waterproof silicone boss 31, the pressing sound-absorbing silicone convex pad 32 and the waterproof silicone wall 33 are all integrally formed on the sealing waterproof silicone pad 3. It can be seen that because the sealing waterproof silicone boss 31, the pressing sound-absorbing silicone convex pad 32 and the waterproof silicone wall 33 are all silicone, they are integrally formed on the sealing waterproof silicone pad 3, which can reduce the production steps and reduce the production cost.

[0029] In this embodiment, the production process of a silent, waterproof and dustproof pluggable electrostatic capacitive keyboard switch includes the following steps: a The plurality of keyboard switches 1 are all limitedly matched with the limiting holes 20 on the fixing plate 2.

[0030] b. Flip the fixing plate 2 , and the sealing and waterproof silicone pad 3 passes through the connecting column 21 to cooperate with the fixing plate and the keyboard switch 1 in a limited manner.

[0031] c The conical induction spring 14 is placed at the bottom of the spring limiting plate 13.

[0032] d. The PCB board 4 passes through the connecting column 21 and is limitedly matched with the sealing waterproof silicone pad 3, and the screw 5 is threadedly matched with the connecting column 21.

[0033] In this embodiment, the working principle of the present invention is as follows: like Figures 1 to 11As shown, when the user presses the key core 11, the key core 11 squeezes the reset straight spring 12 and the conical induction spring 14 downward in turn, and the PCB board 4 receives the change in the size and speed of the capacitance of the conical induction spring, and transmits the signal to the device, thereby realizing the on and off of the keyboard switch. When the user releases the key core 11, the reset straight spring 12 drives the key core 11 to reset under the action of the extrusion elastic force, and reciprocates in turn.

[0034] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
