Description

Technical Field

[0001] The utility model relates to the technical field of keyboards and electronic equipment, and more specifically to the technical field of keyboard structures. Background Art

[0002] Traditional keyboards are widely used in office and gaming scenarios, and are favored by users for their good touch and long service life. However, existing keyboards often have the following problems:

[0003] Inadequate waterproof and dustproofing: Traditional mechanical keyboards typically utilize switches or metal contacts. Because these components are closely spaced, they are susceptible to liquid and dust intrusion. Liquid or dust entering the keyboard can cause key malfunction or poor contact, affecting normal operation. Existing mechanical keyboards struggle to meet these waterproof and dustproof requirements, especially in work environments requiring a high level of protection.

[0004] Key travel is not adjustable: Traditional mechanical keyboards typically have a fixed key travel, and different users have different requirements for key feel and key travel. Some prefer a shorter key travel for a faster response, while others prefer a longer key travel for a better tactile feel. However, existing mechanical keyboards lack adjustable key travel, preventing users from customizing the key travel to their needs.

[0005] Limitations of magnetic triggering: Although some keyboards use magnetic triggering technology (such as using Hall effect sensing) to avoid the wear problem of mechanical contact, they often fail to effectively combine waterproof and dustproof design. Therefore, while achieving magnetic triggering, it is still necessary to resolve the contradiction between key travel and protection performance. Based on the above problems, there is an urgent need for a magnetic mechanical keyboard structure with waterproof and dustproof performance and adjustable key travel to improve the reliability and user experience of the keyboard in different application scenarios. Utility Model Content

[0006] The purpose of the present invention is to provide a keyboard structure in order to solve the technical problems of insufficient waterproof and dustproof performance and unadjustable key stroke of existing keyboards.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] The utility model provides a keyboard structure, comprising a key module and a trigger module; the key module is detachably arranged on the trigger module, and a travel gap capable of accommodating the key travel and having an adjustable spacing exists between the key module and the trigger module.

[0009] In one embodiment, multiple sets of sliding grooves are provided on both side walls of the trigger module from top to bottom, at least one set of snap-fitting protrusions cooperating with the multiple sets of sliding grooves are provided on both sides of the button module, and the bottom surface of the button module and the top surface of the trigger module form a travel gap.

[0010] Specifically, the key module is mechanically connected to the trigger module to ensure adjustable key travel. A designed sliding slot allows for easy repositioning and readjustment of the key module and trigger module, allowing for flexible adjustment of key travel and a personalized user experience.

[0011] In one embodiment, the button module is provided with a plurality of magnetic buttons, the trigger module is a waterproof seal, and a magnetic conduction component corresponding to each magnetic button is provided inside the trigger module.

[0012] Specifically, the key module and trigger module work together to adjust key travel. The trigger module's design ensures complete sealing of internal components, enhancing overall protection against liquid and dust. Magnetic force is used to achieve electrical continuity and signal transmission across the air, effectively preventing electrical leakage and addressing the inadequate protection of existing mechanical keyboards. Through a rational component layout and sealing design, internal components are protected from liquid and dust.

[0013] In one embodiment, the trigger module includes an upper sealing plate, a trigger housing, and a lower sealing plate, wherein the upper sealing plate and the lower sealing plate are provided in a sealing manner at the upper and lower ends of the trigger housing;

[0014] A mounting plate is provided in the trigger housing, a PCB board located above the lower sealing plate is provided at the bottom of the mounting plate, each magnetic flux component is provided on the mounting plate, and each magnetic flux component is electrically connected to the PCB board.

[0015] Specifically, the PCB board is installed at the bottom of the mounting plate of the trigger housing and is sealed by a lower sealing plate; a certain amount of space is reserved inside the lower sealing plate for wiring and heat dissipation of the PCB board; the top of the trigger housing is sealed by an upper sealing plate to ensure that the internal components are completely sealed, thereby improving the protection performance.

[0016] In one embodiment, a mounting plate is provided with a plurality of mounting holes for mounting corresponding magnetic flux components, and the magnetic flux components include two disconnected conductive sheets arranged at the top of the mounting holes, connecting wires respectively connected to the corresponding conductive sheets, an insulating layer arranged below the two conductive sheets, a second magnetic element slidably arranged at the top of the mounting holes, and a third magnetic element fixedly arranged at the bottom of the mounting holes;

[0017] The insulating layer is attached to the top of the second magnetic element, a top limiting hole for limiting the second magnetic element is provided on the top of the mounting hole, and a bottom limiting hole for limiting the third magnetic element is provided on the bottom of the mounting hole;

[0018] Each connecting wire is electrically connected to the PCB board.

[0019] Specifically, the magnetic flux assembly is installed within the mounting hole, with the conductive sheet located at the top of the upper mounting hole. The two conductive sheets remain separated in the normal state and only come into contact when a key is activated. Connecting wires connect the conductive sheets to the PCB to transmit signals.

[0020] A second magnetic element, covered with an insulating layer, is mounted at the top of the mounting hole. The second magnetic element and insulating layer are movably positioned within the top retaining hole below the two conductive plates. The combined thickness of the second magnetic element and insulating layer is less than the depth of the top retaining hole, providing space for the second magnetic element to move vertically. A third magnetic element is mounted and secured within the bottom retaining hole.

[0021] In one embodiment, the key module includes a key plate and a plurality of key holes arranged on the key plate, each magnetic key is arranged in a corresponding key hole, and each magnetic key is installed at the corresponding key hole.

[0022] In one embodiment, each magnetic key includes a key cap, a guide inner cylinder fixedly disposed in the key cap, a guide outer cylinder fixedly disposed outside the corresponding key hole on the key plate, a guide post disposed in the guide inner cylinder, a spring sleeved on the guide post, and a first magnetic element disposed at the bottom of the guide post.

[0023] The guide inner cylinder is slidably clamped in the guide outer cylinder, the upper end of the spring is fixed on the guide column, and the lower end is fixed on the guide outer cylinder.

[0024] Specifically, the keypad features holes that allow the keycap and its first magnetic element to move freely up and down during a press, ensuring smooth vertical movement of both during operation. When the keycap is installed on the keypad, the spring is securely fastened within the keypad's designed cavity, ensuring the spring remains stable during operation without deflection or loosening, thus ensuring precise rebound and smooth key operation.

[0025] The travel gap provides ample space for the keycap and first magnetic element to move up and down, while also allowing for adjustment of the key travel. This structural design allows for easy replacement of the spring, thereby adjusting the key's pressing force to suit different user preferences and tactile requirements.

[0026] When the key travel is adjusted to its lowest setting, the spring force significantly outweighs the combined weight of the keycap and the first magnetic element, as well as the attraction between the first and second magnetic elements. This design ensures that the spring fully supports the key's rebound at the minimum actuation position, ensuring sensitive and reliable key operation.

[0027] In one embodiment, the magnetic directions of the first magnetic element, the second magnetic element and the third magnetic element are the same, and adjacent two magnetic elements attract each other.

[0028] Specifically, the first magnetic element, the second magnetic element and the third magnetic element are arranged in the keycap bottom, the top limiting hole and the bottom limiting hole in turn from top to bottom, and the magnetic directions of the three are the same and attract each other; the connecting line is fixed in the trigger shell and connected with the two conductive sheets, and the surface of the second magnetic element is covered with an insulating layer. The second magnetic element moves up and down in the top limiting hole, thereby realizing the closing and opening of the conductive sheets.

[0029] A limiting structure is arranged below the top limiting hole for limiting the lower limit of displacement of the second magnetic element. The limiting structure ensures that the second magnetic element and the third magnetic element maintain a certain distance, thereby avoiding direct contact between the two.

[0030] In one embodiment, each group of sliding grooves includes grooves symmetrically arranged on the left and right sides of the trigger shell, and each groove end is provided with a limiting block for limiting the position of the clamping protrusion.

[0031] The working process is as follows:

[0032] The third magnetic element is located below the second magnetic element. In the natural state, the second magnetic element approaches the third magnetic element under the attraction of the third magnetic element until it stops at the bottom of the top limiting hole.

[0033] When the keycap is pressed, the distance between the first magnetic element and the second magnetic element will change, thereby changing the force condition of the second magnetic element. The attraction between the third magnetic element and the second magnetic element is smaller than the attraction between the second magnetic element and the first magnetic element, the second magnetic element moves towards the first magnetic element, the conductive sheet contacts and realizes circuit closing.

[0034] In one embodiment, the material of the upper sealing plate is sound insulation material.

[0035] Specifically, the upper sealing plate can be selected from a variety of materials according to actual needs, such as polyurethane foam, rubber or other materials suitable for waterproof, dustproof and sound insulation (the material of the upper sealing plate can also be selected from different materials such as hard plastic or thin layer resonance film according to needs to increase the sound effect), so as to improve the overall performance and user experience of the keyboard. The lower magnetic conduction assembly can be replaced with a Hall element or other similar components to realize corresponding functions.

[0036] The beneficial effects of the utility model are as follows:

[0037] 1. The key module and trigger module work together to adjust key travel. The trigger module's design ensures complete sealing of internal components, enhancing overall protection against liquid and dust. Magnetic force is used to achieve continuity and signal transmission across the air, effectively preventing electrical leakage and addressing the inadequate protection of existing mechanical keyboards. Through rational component layout and sealing design, internal components are protected from liquid and dust.

[0038] 2. The travel gap provides ample space for the up-and-down movement of the keycap and the first magnetic element, while also allowing for adjustment of the key travel. This structural design allows for easy replacement of the spring, thereby adjusting the key's pressing force to meet different user preferences and feel requirements.

[0039] 3. The keypad is equipped with holes that allow the keycap and its first magnetic element to move freely up and down during pressing, ensuring smooth vertical movement of both during operation. When the keycap is installed on the keypad, the spring is firmly fixed in the cavity designed into the keypad, ensuring that the spring remains stable during operation without deflection or loosening, thereby ensuring precise rebound and smooth operation of the key.

[0063] Example 1

[0064] like Figures 1 to 13 As shown, this embodiment provides a keyboard structure, including a key module 1 and a trigger module 2; the key module 1 is detachably arranged on the trigger module 2, and there is a travel gap between the key module 1 and the trigger module 2 that can accommodate the key travel and the spacing is adjustable.

[0065] Specifically, the design of the keyboard structure is flexible and diverse. Its appearance can be designed into different shapes such as ellipse, semicircle, etc. according to the actual usage environment to provide a personalized usage experience.

[0066] Example 2

[0067] This embodiment is a further optimization based on the embodiment 1, specifically:

[0068] Multiple sets of sliding grooves 402 are set on the two side walls of the trigger module 2 from top to bottom, and at least one set of clamping protrusions 401 cooperating with the multiple sets of sliding grooves are set on both sides of the button module 1.

[0069] Specifically, the key module 1 is mechanically connected to the trigger module 2 to ensure that the key travel is adjustable. The designed sliding groove 402 can easily reassemble and adjust the matching position between the key module and the trigger module, thereby flexibly adjusting the key travel and achieving a personalized user experience.

[0070] The positions and sizes of the engaging protrusion 401 and the sliding groove 402 can be flexibly adjusted to suit different usage requirements and structural layouts.

[0071] Example 3

[0072] This embodiment is a further optimization based on the second embodiment, specifically:

[0073] The button module 1 is provided with a plurality of magnetic buttons, the trigger module 2 is a waterproof seal, and a magnetic conduction component 3 corresponding to each magnetic button is provided inside the trigger module 2 .

[0074] Specifically, the key module 1 and trigger module 2 work together to adjust the key travel. The design of the trigger module 2 ensures that the internal components are completely sealed, thereby improving overall protection and preventing liquid and dust from invading the internal components. Magnetic force is used to achieve conduction and signal transmission across the air, effectively preventing electrical leakage and addressing the inadequate protection of existing mechanical keyboards. Through a rational component layout and sealing design, the internal components are protected from liquid and dust.

[0075] Example 4

[0076] This embodiment is a further optimization based on the embodiment 1, specifically:

[0077] The trigger module 2 includes an upper sealing plate 21, a trigger housing 22 and a lower sealing plate 24. The upper sealing plate 21 and the lower sealing plate 24 are sealed and arranged at the upper and lower ends of the trigger housing 22.

[0078] A mounting plate is provided in the trigger housing 22 , and a PCB board 23 located above the lower sealing plate 24 is provided at the bottom of the mounting plate. Each magnetic flux component 3 is provided on the mounting plate, and each magnetic flux component 3 is electrically connected to the PCB board 23 .

[0079] Specifically, the PCB board 23 is installed at the lower part of the mounting plate of the trigger housing 22 and is sealed by the lower sealing plate 24; a certain amount of space is reserved inside the lower sealing plate 24 for wiring and heat dissipation of the PCB board 23; the top of the trigger housing 22 is sealed by the upper sealing plate 21 to ensure that the internal components are completely sealed, thereby improving the protection performance.

[0080] Example 5

[0081] This embodiment is a further optimization based on the embodiment 4, specifically:

[0082] The mounting plate is provided with a plurality of mounting holes for mounting corresponding magnetic flux components 3. The magnetic flux components 3 include two disconnected conductive sheets 31 provided at the top of the mounting holes, connecting wires 32 respectively connected to the corresponding conductive sheets 31, an insulating layer 33 provided below the two conductive sheets 31, a second magnetic element 6 slidably provided at the top of the mounting holes, and a third magnetic element 7 fixedly provided at the bottom of the mounting holes.

[0083] The insulating layer 33 is attached to the top of the second magnetic element 6. The top of the mounting hole is provided with a top limiting hole for limiting the second magnetic element 6. The bottom of the mounting hole is provided with a bottom limiting hole for limiting the third magnetic element 7.

[0084] Each connecting wire 32 is electrically connected to the PCB board 23 .

[0085] Specifically, the magnetic flux assembly 3 is installed in the mounting hole, with the conductive sheet 31 located at the top of the upper mounting hole. The two conductive sheets 31 remain separated in the normal state and only come into contact when a key is activated. A connecting wire 32 connects the conductive sheets 31 to the PCB 23 for signal transmission.

[0086] A second magnetic element 6 is mounted at the top of the mounting hole, along with an insulating layer 33. The second magnetic element 6 and insulating layer 33 are movably positioned within the top retaining hole below the two conductive sheets 31. The combined thickness of the second magnetic element 6 and insulating layer 33 is less than the depth of the top retaining hole, providing space for the second magnetic element 6 to move vertically. A third magnetic element 7 is mounted and secured within the bottom retaining hole.

[0087] Example 6

[0088] This embodiment is a further optimization based on the embodiment 5, specifically:

[0089] The key module 1 includes a key plate 13 and a plurality of key holes arranged on the key plate 13 . Each magnetic key is arranged in a corresponding key hole, and each magnetic key is installed at the corresponding key hole.

[0090] Each magnetic key comprises a key cap, a guide inner cylinder fixedly disposed in the key cap, a guide outer cylinder fixedly disposed on the outside of the corresponding key hole on the key plate 13, a guide post disposed in the guide inner cylinder, a spring 12 sleeved on the guide post, and a first magnetic element 5 disposed at the bottom of the guide post.

[0091] The guide inner cylinder is slidably engaged in the guide outer cylinder. The upper end of the spring 12 is fixed on the guide column, and the lower end is fixed on the guide outer cylinder.

[0092] Specifically, the keypad 13 is provided with holes that allow the keycap 11 and its first magnetic element 5 to move freely up and down during pressing, ensuring smooth vertical movement of both during operation. When the keycap 11 is installed on the keypad 13, the spring 12 is securely fixed within the cavity designed for the keypad 13, ensuring that the spring 12 remains stable during operation without deflection or loosening, thereby ensuring precise rebound and smooth operation of the key.

[0093] The travel gap provides ample space for the up-and-down movement of the keycap 11 and the first magnetic element 5, while also allowing for adjustment of the key travel. This structural design allows for easy replacement of the spring 12, thereby adjusting the key's pressing force to suit varying user preferences and tactile requirements. When not pressed, the upper portion of the gap forms a flat surface, ensuring the overall structure's aesthetics and functionality.

[0094] When the key travel is adjusted to its lowest position and keycap 11 is pressed, the elastic force of spring 12 is significantly greater than the combined weight of keycap 11 and first magnetic element 5, as well as the attractive force between first magnetic element 5 and second magnetic element 6. This design ensures that at the minimum trigger position, spring 12 can fully support the key's rebound, ensuring sensitive and reliable key operation.

[0095] The key cap 11 and the spring 12 can be eliminated, and a soft and resilient material can be used to fix the first magnetic element 5, so as to provide better adaptability when meeting different tactile sensations and pressing force requirements.

[0096] Example 7

[0097] This embodiment is a further optimization based on the embodiment 6, specifically:

[0098] The magnetic directions of the first magnetic element 5 , the second magnetic element 6 and the third magnetic element 7 are the same, and two adjacent magnetic elements attract each other.

[0099] Specifically, the first magnetic element 5, the second magnetic element 6, and the third magnetic element 7 are arranged in the bottom, top, and bottom limit holes of the keycap 11, respectively, from top to bottom. Their magnetic orientation is the same, attracting each other. A connecting wire 32 is secured within the trigger housing 22 and connected to the two conductive plates 31. The surface of the second magnetic element 6 is covered with an insulating layer 33. The second magnetic element 6 moves up and down within the top limit hole, thereby closing and opening the conductive plates 31.

[0100] A limiting structure is provided below the top limiting hole to limit the lower limit of the displacement of the second magnetic element 6. The limiting structure ensures that a certain distance is maintained between the second magnetic element 6 and the third magnetic element 7, thereby avoiding direct contact between the two.

[0101] Example 8

[0102] This embodiment is a further optimization based on the embodiment 7, specifically:

[0103] Each group of sliding grooves 402 includes grooves symmetrically arranged on the left and right sides of the trigger housing 22, and a limiting block is provided at the end of each groove to limit the position of the engaging protrusion.

[0104] The design of the sliding groove 4.2 has a limiting and positioning function, which can effectively limit the movement range of this structure during the adjustment process, and ensure the precise fit between the button module and the trigger module to prevent accidental falling off or excessive displacement.

[0105] Example 9

[0106] This embodiment is a further optimization based on the embodiment 7, specifically:

[0107] The upper sealing plate 21 is made of sound insulation material.

[0108] Specifically, the upper sealing plate can be made of a variety of materials according to actual needs, such as polyurethane foam, rubber or other materials suitable for waterproof, dustproof and sound insulation, so as to improve the overall performance and user experience of the keyboard.

[0109] The lower magnetic conduction component 3 can be replaced by a Hall element or other similar components to achieve corresponding functions.

[0110] The working process is as follows:

[0111] The third magnetic element 7 is located below the second magnetic element 6 . In a natural state, the second magnetic element 6 approaches the third magnetic element 7 under the attraction of the third magnetic element 7 until it stops at the bottom of the top limiting hole.

[0112] When the button cap 11 is pressed, the distance between the first magnetic element 5 and the second magnetic element 6 will change, thereby changing the force applied to the second magnetic element 6. The attraction between the third magnetic element 7 and the second magnetic element 6 is smaller than the attraction between the second magnetic element 6 and the first magnetic element 5. The second magnetic element 6 moves toward the first magnetic element 5, and the conductive sheet 31 contacts and closes the circuit.
