Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] Please refer to the following: Figures 1 to 5The keyboard provided in this application embodiment will now be described. The keyboard includes a bottom cover 10, a flexible sealing cover 20, and keys 40. The flexible sealing cover 20 is disposed on the bottom cover 10 and cooperates with the bottom cover 10 to form a sealed cavity 30. The flexible sealing cover 20 has an assembly port 21 communicating with the sealed cavity 30. The keys 40 include keycaps 41 and key shafts 42. The keycaps 41 are disposed outside the flexible sealing cover 20 and are correspondingly disposed with respect to the assembly port 21. The key shafts 42 are disposed inside the sealed cavity 30, with one end of the key shafts 42 passing through the assembly port 21 and extending outside the flexible sealing cover 20, and connecting with the keycaps 41. The key shafts 42 are sealed to the assembly port 21.

[0036] The advantages of the keyboard provided in this application are as follows: Compared with the prior art, by opening an assembly port 21 on the flexible sealing cover 20 to connect with the sealing cavity 30, a portion of the key switch 42 extends outside the flexible sealing cover 20 through the assembly port 21 and connects with the keycap 41. The key switch 42 is sealed to the assembly port 21, making the key switch 42 and the flexible sealing cover 20 an integral unit. Thus, when the user presses the keycap 41 to actuate the key switch 42, the surrounding part of the flexible sealing cover 20 connected to the key switch 42 also moves with the key switch 42. The sealed connection between the key switch 42 and the assembly port 21 of the flexible sealing cover 20 effectively prevents external dust and liquids from entering the sealing cavity 30 through the assembly port 21, resulting in better waterproof and dustproof performance of the keyboard, which is beneficial to ensuring the quality, service life, and safety of the keyboard. By placing the keycap 41 outside the flexible sealing cover 20, it is beneficial to ensure the tactile feel of the user pressing the keycap 41, making it easier for the user to operate.

[0037] It should be noted that the bottom cover 10 is a rigid structure, which enables the bottom cover 10 to provide sufficient support for each component and effectively improve the stability of the overall keyboard structure.

[0038] In this embodiment, the bottom cover 10 is generally rectangular in shape.

[0039] Please see Figure 2 and Figure 3 Specifically, the bottom cover 10 includes a bottom plate 11 and a frame 12. The frame 12 extends from the periphery of the bottom plate 11 toward the side where the flexible sealing cover 20 is located. The frame 12 is arranged around the periphery of the bottom plate 11 and is sealed to the flexible sealing cover 20.

[0040] Furthermore, the frame 12 and the base plate 11 are integrally formed, which effectively ensures the sealing of the bottom cover 10.

[0041] In some embodiments, the base plate 11 is a rectangular plate and the frame 12 is a rectangular frame. Of course, in other embodiments, the bottom cover 10 can also be designed into other shapes as needed. For example, the cross-section of the bottom cover 10 is circular, that is, the base plate 11 is a circular plate and the frame 12 is a circular frame.

[0042] Please see Figure 2and Figure 3 The keyboard also includes a pressure frame 70 and a clamping frame 80. The pressure frame 70 is sealed to the edge of the bottom cover 10. The clamping frame 80 is disposed in the sealing cavity 30 and is correspondingly connected to the pressure frame 70. The edge of the flexible sealing cover 20 is clamped between the pressure frame 70 and the clamping frame 80. Specifically, the edges of the pressure frame 70, the clamping frame 80 and the flexible sealing cover 20 are connected together by screws.

[0043] Please see Figure 1 and Figure 2 The flexible sealing cover 20 is a sheet-like silicone material. Understandably, the sheet-like nature of the flexible sealing cover 20, made of silicone, gives it good softness, elasticity, and fluidity. This effectively ensures the smooth movement of the flexible sealing cover 20 with the button 40, preventing resistance when the button 40 is pressed and allowing for easy activation of the button 40, thus improving the user experience. Furthermore, by making the flexible sealing cover 20 from silicone, the sealing between the flexible sealing cover 20 and the bottom cover 10, the button 40, the pressure frame 70, and the clamping frame 80 is effectively guaranteed.

[0044] In some embodiments, the portion of the flexible sealing cover 20 corresponding to the keycap 41 extends outward to form a boss 22. Specifically, the boss 22 is the portion of the panel 23 corresponding to the keycap 41, and the mounting opening 21 is formed on the boss 22. By extending the portion of the flexible sealing cover 20 corresponding to the keycap 41 outward, the keycap 41 is positioned at a higher level, which helps to further improve the feel of the user pressing the keycap 41 and enhances the user experience.

[0045] It should be noted that the shape of the outer surface of the boss 22 with the assembly opening 21 is not limited. The outer surface of the boss 22 with the assembly opening 21 is flat. Alternatively, the outer surface of the boss 22 with the assembly opening 21 may be recessed inward. Or, the outer surface of the boss 22 with the assembly opening 21 may be protruding outward.

[0046] In this embodiment, there are multiple buttons 40, which are distributed at preset intervals, and different buttons 40 are used to trigger different functions. The number of mounting openings on the flexible sealing plate 440 is equal to the number of buttons 40, and they are set in a one-to-one correspondence.

[0047] The orthographic projections of the keycap 41 and the boss 22 overlap on the same plane. Specifically, the orthographic projection of the boss 22 falls within the orthographic projection range of the keycap 41, meaning the keycap 41 completely covers the boss 22. By protecting the boss 22 with the keycap 41, external dust is less likely to fall onto the boss 22 or liquid is less likely to flow onto the boss 22. This further prevents external dust and liquid from entering the sealed cavity 30 through the assembly port 21, which helps to further improve the keyboard's waterproof and dustproof performance.

[0048] Please see Figure 2 and Figure 4 The keycap 41 is basin-shaped. Specifically, the keycap 41 includes a pressing part 410 and a cover edge 411. The cover edge 411 extends from the circumferential edge of the pressing part 410 toward the side where the flexible sealing cover 20 is located. The pressing part 410 is provided corresponding to the mounting port 21 and connected to the key shaft 42, that is, the pressing part 410 is provided corresponding to the boss 22.

[0049] Furthermore, the pressing part 410 has a slightly concave arc-shaped structure towards the flexible sealing cover 20, which conforms to ergonomic principles and helps to further improve the user's fingertip feel when touching the pressing part 410. The cover edge 411 is arranged around the periphery of the pressing part 410 and gradually expands from the pressing part 410 towards the side where the flexible sealing cover 20 is located, so that the keycap 41 is basin-shaped. Understandably, the cover edge 411 is inclined relative to the pressing part 410. The inclined cover edge 411 has a guiding function, which can guide dust or liquid on the cover edge 411 to the flexible sealing cover 20 outside the keyboard or between the bosses 22, which helps to further prevent dust and liquid from flowing onto the bosses 22.

[0050] In some embodiments, the keycap 41 is detachably connected to the key switch 42, facilitating keycap 41 replacement. Understandably, by detachably connecting the keycap 41 to the key switch 42, when the keycap 41 is damaged, its markings are worn and need replacement, or when dust or stains accumulate on the keycap and need cleaning, the keycap 41 can be directly removed from the key switch 42 for replacement or cleaning, improving the keyboard's usability. Of course, in other embodiments, the keycap 41 can also be fixedly connected to the key switch 42, effectively ensuring the stability of the connection between the keycap 41 and the key switch 42.

[0051] Please refer to the figure. Figure 2 , Figure 4 and Figure 5 Specifically, the keycap 41 has a key core 412 on the side facing the flexible sealing cover 20. The key shaft 42 includes a shaft body 43 and a bracket 44 connecting the shaft body 43. The shaft body 43 is located in the sealing cavity 30. One end of the bracket 44 passes through the assembly port 21 and extends out of the flexible sealing cover 20, and is inserted into the key core 412.

[0052] Furthermore, the bracket 44 includes a sealing plate 440 and a connecting post 441. The sealing plate 440 is correspondingly disposed with the assembly port 21 and is sealed and fitted to the inner surface of the flexible sealing cover 20, which helps to ensure the sealing performance between the bracket 44 and the assembly port 21. The connecting post 441 is connected to the sealing plate 440 and is inserted into the keycap 41.

[0053] In some embodiments, the key core 412 is provided with a keyway 413 for the connecting post 441 to be inserted into, and the connecting post 441 and the keyway 413 on the key core 412 are interference-fitted. Further, the keyway 413 is a cross-shaped groove, and the connecting post 441 is a cross-shaped shaft. The key core 412 and the connecting post 441 are connected by the cross-shaped groove and the cross-shaped shaft, effectively ensuring the stability of the connection between the key core 412 and the connecting post 441.

[0054] To remove the keycap 41 from the key switch 42, simply pull the keycap 41 upwards to disengage the key groove 413 on the key core 412 from the connecting post 441, thereby separating the keycap 41 from the key switch 42. To install the keycap 41 onto the key switch 42, align the key groove 413 on the key core 412 with the connecting post 441, and press the keycap 41 downwards to insert the connecting post 441 into the key groove 413 on the key core 412.

[0055] In other embodiments, the connecting post 441 is provided with a keyway 413 for the key core 412 to be inserted into, and the key core 412 is interference-fitted with the keyway 413 on the connecting post 441. Further, the keyway 413 is a cross-shaped groove, and the key core 412 is a cross-shaped shaft.

[0056] Furthermore, the sealing plate 440 is located within the sealing cavity 30. The sealing plate 440 has a first sealing ring 444 and a second sealing ring 445 on its side facing the flexible sealing cover 20. The first sealing ring 444 surrounds the second sealing ring 445 and is spaced apart from it. Both the first sealing ring 444 and the second sealing ring 445 seal against the inner surface of the flexible sealing cover 20 to ensure a tight seal between the sealing plate 440 and the flexible sealing cover 20. Optionally, the sealing plate 440, the first sealing ring 444, and the second sealing ring 445 are integrally formed.

[0057] In some embodiments, an adhesive layer is provided between the inner surfaces of the sealing plate 440 and the flexible sealing cover 20. By providing an adhesive layer between the inner surfaces of the sealing plate 440 and the flexible sealing cover 20, the sealing performance of the key shaft 42 to the assembly port 21 is effectively guaranteed. Optionally, the adhesive layer can be double-sided adhesive.

[0058] The bracket 44 also includes a positioning post 442 connecting the sealing plate 440, the positioning post 442 being located on the side of the sealing plate 440 facing away from the flexible sealing plate 440. A transition post 430 is provided on the shaft 43, and the transition post 430 is inserted into the positioning post 442. In this embodiment, the positioning post 442 and the sealing plate 440 are integrally formed.

[0059] Specifically, the positioning post 442 is provided with a positioning groove 443 for the adapter post 430 to be inserted into, and the adapter post 430 and the positioning groove 443 on the positioning post 442 are interference-fitted. Further, the positioning groove 443 is a cross groove, and the adapter post 430 is a cross shaft. Alternatively, the adapter post 430 is provided with a positioning groove 443 for the positioning post 442 to be inserted into, and the positioning post 442 and the positioning groove 443 on the adapter post 430 are interference-fitted. Further, the positioning groove 443 is a cross groove, and the positioning post 442 is a cross shaft.

[0060] In some embodiments, the bracket 44 further includes a fastening plate 446 corresponding to the mounting port 21. The fastening plate 446 is connected between the sealing plate 440 and the connecting post 441, and is sealed to the outer surface of the flexible sealing cover 20. Understandably, by cooperating with the sealing plate 440, the peripheral portion of the flexible sealing cover 20 corresponding to the mounting port 21 is pressed tightly between the fastening plate 446 and the sealing plate 440, which helps to further ensure the sealing performance between the bracket 44 and the mounting port 21.

[0061] Specifically, the fastening plate 446 is located between the boss 22 and the keycap 41, and the fastening plate 446 is in close contact with the outer surface of the boss 22. The fastening plate 446 has a protrusion 447 on the side facing the mounting opening 21, and the protrusion 447 passes through the mounting opening 21 and connects to the side of the sealing plate 440 facing the mounting opening 21. Optionally, the protrusion 447 and the sealing plate 440 can be connected by ultrasonic welding, laser welding, adhesive bonding or hot melt bonding.

[0062] Furthermore, the protrusion 447 is adapted to the assembly port 21.

[0063] Furthermore, the protrusion 447 is provided with a slot 448, and the sealing plate 440 has a protrusion 449 on the side facing the assembly port 21. The protrusion 449 is inserted into the slot 448 to ensure the stability of the connection between the fastening plate 446 and the sealing plate 440. The connecting post 441 is connected to the side of the fastening plate 446 away from the assembly port 21. In this embodiment, the connecting post 441 and the fastening plate 446 are integrally formed.

[0064] The keyboard also includes a spring-loaded element housed within the sealed cavity 30 and located between the bottom of the switch 43 and the base plate 11. This spring-loaded element elastically pushes the key 40 back to its original position when pressed, ensuring that the next press of the key 40 triggers the corresponding command. Optionally, the spring-loaded element can be a sheet or a spring.

[0065] In this embodiment, a guide post 431 is provided at the bottom of the shaft 43, and the elastic element is a helical spring, which is sleeved on the guide post 431. When a pressing force is applied to the button 40, the shaft 43 is pushed downward to elastically compress the elastic element. When the pressing force on the button 40 is released, the elastic element elastically expands, pushing the shaft 43 upward to reset the button 40.

[0066] In some embodiments, the keyboard further includes a control board 50 disposed within a sealed cavity 30. The control board 50 is located on the inner side of the bottom cover 10, specifically on the inner side of the base plate 11. The bottom of the key shaft 42 corresponds to a preset area on the control board 50, such that when the key 40 is pressed, the key shaft 42 contacts the control board 50, triggering a preset command on the control board 50. The control board 50 is provided with a through hole 51 for the guide post 431 to pass through. Further, the control board 50 is a PCB or a PCBA.

[0067] The keyboard also includes an assembly plate 60 disposed within a sealed cavity 30, the assembly plate 60 being located between the control plate 50 and the flexible sealing cover 20.

[0068] The assembly plate 60 is provided with a limiting opening 61 for the key shaft 42 to pass through. The limiting opening 61 is used to limit and guide the key shaft 42 when it moves up and down, preventing the key shaft 42 from deflecting and effectively ensuring the accuracy of the preset commands triggered by the key shaft 42 on the control plate 50. When the key shaft 42 moves to the preset position, the key shaft 42 is locked on the side of the assembly plate 60 away from the control plate 50, so as to limit the downward stroke of the key shaft 42 and prevent the key shaft 42 from pressing the control plate 50 excessively and causing wear to the control plate 50. Specifically, the shaft body 43 has an extension 432 on its periphery. The extension 432 is located on the side of the assembly plate 60 away from the control plate 50. When the button 40 is pressed and moves downward to the preset position, the extension 432 is locked on the periphery of the limiting opening 61 away from the control plate 50.

[0069] Please refer to the following: Figures 6 to 8 This is another embodiment of a keyboard according to this application. The keyboard includes a bottom cover 10, a flexible sealing cover 20, and keys 40. The bottom cover 10 includes a base plate 11 and a frame 12. The flexible sealing cover 20 includes a panel 23 and a fixing frame 24 extending from the circumferential edge of the panel 23 toward the bottom cover 10. The fixing frame 24 is disposed around the periphery of the panel 23 and is sealed to the bottom cover 10. Further, the fixing frame 24 has an outwardly bent skirt 25 near the end away from the panel 23, and the skirt 25 is sealed to the frame 12 so that the flexible sealing cover 20 and the bottom cover 10 cooperate to form a sealing cavity 30. Optionally, the skirt 25 and the frame 12 are bonded together with adhesive, which helps to ensure the stability and sealing of the connection between the flexible sealing cover 20 and the bottom cover 10.

[0070] It should be noted that in other embodiments, the fixing frame 24 may also cover the outside of the frame 12, that is, the inner surface of the fixing frame 24 is sealed and fitted with the outer surface of the frame 12, which is more conducive to ensuring the sealing performance between the sealing cover and the bottom cover 10.

[0071] The key 40 includes a keycap 41 and a key switch 42. The key switch 42 includes a switch body 43 and a bracket 44 connecting the switch body 43. The switch body 43 is located inside the sealed cavity 30. One end of the bracket 44 extends out of the flexible sealing cover 20 through the assembly port 21 and is inserted into the key core 412 of the keycap 41. When the key core 412 is inserted with the bracket 44, the end of the key core 412 away from the keycap 41 is pressed tightly against the outer surface of the flexible sealing cover 20. More specifically, one end of the key core 412 is connected to the pressing part 410, and the other end of the key core 412 is pressed tightly against the outer surface of the boss 22. The flexible sealing cover 20 seals the key core 412, effectively further improving the sealing performance of the assembly port 21.

[0072] Please see Figure 7 and Figure 8 The bracket 44 includes a sealing plate 440 and a connecting post 441. The sealing plate 440 is correspondingly disposed with the assembly port 21 and is sealed and fitted to the inner surface of the flexible sealing cover 20. The connecting post 441 is connected to the sealing plate 440 and is inserted into the keycap 41. Specifically, the sealing plate 440 is located inside the sealing cavity 30, one end of the connecting post 441 is connected to the side of the sealing plate 440 facing the assembly port 21, and the other end extends out of the flexible sealing cover 20 through the assembly port 21 and is inserted into the keycap 41.

[0073] It should be noted that when the connecting post 441 is a cross shaft, the assembly port 21 on the flexible sealing cover 20 is a cross-shaped opening through which the connecting post 441 can pass.
