Description

Technical Field

[0001] This invention relates to the field of industrial keyboard technology, and more specifically to a mechanical keyboard with uniform damping. Background Technology

[0002] In modern industrial production, many operations need to be carried out in high-temperature environments, such as metallurgy, glass manufacturing, and casting. In these high-temperature environments, workers need to frequently input instructions and data through industrial keyboards to control the operation of production equipment.

[0003] Existing industrial keyboards fail to adequately consider the special needs of operators wearing gloves. Given the threat to workers' hand safety in high-temperature environments, heat-resistant gloves are essential. However, these gloves are typically thick and heavy, leading to frequent accidental keystrokes. While some industrial keyboards exist that prevent accidental keystrokes, they achieve this by applying internal air pressure to create resistance on the keycaps. However, because the airflow channels are integrated, keycaps closer to the fan experience stronger pressure than those further away, resulting in inconsistent resistance. This uneven pressure can cause operators to misjudge keystrokes, ultimately impacting the efficiency of equipment control.

[0004] In summary, the existing technology for industrial keyboards suffers from uneven damping to prevent accidental touches, resulting in inconsistent tactile feedback and potentially causing operational misjudgments. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a mechanical keyboard with uniform damping, which solves the technical problem in the prior art where the anti-accidental touch damping of industrial keyboards is uneven, resulting in inconsistent operating feel and potentially causing operational misjudgment.

[0006] To achieve the above-mentioned technical objectives, this application adopts the following technical solution: This application provides a mechanical keyboard with uniform damping, comprising: Keyboard body; Multiple keycaps are mounted on the keyboard body; Multiple anti-mistouch mechanisms are provided, each corresponding to one of the keycaps. Each anti-mistouch mechanism includes a hinge, a guide, and a resistance-increasing component. The hinge is linked to the keycap, the guide is hinged to the keyboard body, and the guide is movably connected to the hinge. The resistance-increasing component is mounted on the guide and is used to increase the pressing resistance of the corresponding keycap. A control module, electrically connected to the anti-mistouch mechanism, is used to send a command to the resistance-increasing component of the anti-mistouch keycap when the target keycap is pressed. The anti-mistouch keycap is a keycap that is directly adjacent to the target keycap in spatial position.

[0007] In some embodiments of this application, the resistance-increasing component includes a first memory alloy spring and a second memory alloy spring, both of which are electrically connected to the control module. The first shape memory alloy spring contracts when energized to release the limiting state of the resistance-increasing component; the second shape memory alloy spring extends when energized to drive the resistance-increasing component to produce a resistance-increasing effect.

[0008] In some embodiments of this application, the guide member is provided with two electrical contacts, both of which are signal-connected to the control module and electrically connected to the first memory alloy spring and the second memory alloy spring, respectively.

[0009] In some embodiments of this application, the resistance-increasing component includes a guide shaft and an inclined block fixed on the guide shaft. The hinge has an inclined groove adapted to the inclined block, and the inclined block engages in the inclined groove to form a mechanical limit. The first memory alloy spring is connected to the guide shaft. When it is energized and contracts, it drives the guide shaft to move, causing the tilting block to disengage from the tilting groove, thereby releasing the limiting position.

[0010] In some embodiments of this application, the resistance-increasing assembly further includes a mounting plate and a resistance-increasing guide sleeve, wherein the first memory alloy spring, the second memory alloy spring, and the guide shaft are all mounted on the mounting plate, and the guide shaft slides within the resistance-increasing guide sleeve.

[0011] In some embodiments of this application, the guide includes a bent plate and a hinge shaft, the bent plate being pivotally connected to the keyboard body via the hinge shaft; When the limit is released, the guide can rotate around the hinge axis, causing the resistance-increasing component to separate from the keyboard body.

[0012] In some embodiments of this application, the hinge member is provided with a ball joint and a hinge groove, and the guide member forms a ball joint connection with the hinge member through the cooperation of the ball joint and the hinge groove.

[0013] In some embodiments of this application, the keycap has a pad and a key shaft at its bottom, the hinge is connected to the pad, and the keyboard body has a mounting hole at the mounting position of each keycap, with the key shaft passing through the mounting hole.

[0014] In some embodiments of this application, the resistance-increasing component includes a rubber ball, and a corresponding rubber washer is provided on the keyboard body. The rubber ball and the rubber washer are in close compression contact, and the rubber washer is disposed on the inner wall of the mounting hole.

[0015] In some embodiments of this application, multiple anti-mistouch mechanisms are evenly distributed on the outer side of each keycap for alternating operation or redundant backup; the control module calls one or a portion of the multiple anti-mistouch mechanisms corresponding to the same keycap to operate.

[0016] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include: This application achieves precise and uniform resistance increase for all non-target keys by configuring an independent anti-mistouch mechanism for each keycap, which is uniformly coordinated by a central control module. This design fundamentally solves the problem of accidental operation caused by uneven damping, ensuring that the anti-mistouch feel of each key remains highly consistent even under special conditions such as wearing gloves. This helps operators develop stable muscle memory, thereby improving work efficiency and operational safety. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Directional terms such as "upper," "lower," "left," and "right" refer to exemplary directions based on the accompanying drawings. Features specified as "first" or "second" implicitly include one or more of that feature. Singular expressions can also be used in plural forms. "Multiple" means two or more. The terms "installed," "connected," and "linked" can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection via an intermediate medium, and it can be a connection within two components. Furthermore, "linked" can include wireless connections.

[0021] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a mechanical keyboard with uniform damping, which solves the technical problem in the prior art where the anti-accidental touch damping of industrial keyboards is uneven, resulting in inconsistent operating feel and potentially causing operational misjudgment.

[0022] To achieve the above-mentioned technical objectives, this application adopts the following technical solution: Reference Figures 1 to 7 The present invention provides a mechanical keyboard with uniform damping, comprising: a keyboard body 1, a plurality of keycaps 2 disposed on the keyboard body 1, at least one anti-mistouch mechanism 3 disposed in one-to-one correspondence with each keycap 2, and a control module 4.

[0023] Specifically, the keyboard body 1 serves as the base for the entire keyboard, providing a mounting platform for other components. Multiple keycaps 2 are conventionally arranged on the keyboard body 1, each keycap 2 corresponding to a key switch (a mechanical switch as shown by key switch 202 in the figure). The core of this invention lies in the independent configuration of an anti-mistouch mechanism 3 for each keycap 2. This anti-mistouch mechanism 3 is an electromechanical integrated module, its structure including a hinge 301 linked to the keycap 2, a guide 302 hinged to the keyboard body 1, and a resistance-increasing component 303 mounted on the guide 302. The guide 302 and the hinge 301 are movably connected, allowing the resistance-increasing component 303 to perform precise actions according to commands.

[0024] The control module 4, typically a microcontroller (MCU) or dedicated chip integrated on the keyboard PCB, is electrically connected to the trigger signals of all keycaps 2 and all anti-mistouch mechanisms 3. Its core function is: when any "target keycap" is detected to be effectively pressed (i.e., a key signal is triggered), the control module 4 immediately sends a start command to the anti-mistouch mechanisms 3 corresponding to all "anti-mistouch keycaps," activating their resistance-increasing components 303, thereby instantaneously increasing the pressing resistance of these anti-mistouch keycaps. These anti-mistouch keycaps are those directly adjacent to the target keycap in spatial position.

[0025] By configuring an independent anti-mistouch mechanism for each keycap and coordinating it uniformly with a central control module, precise and uniform resistance is applied to non-target keys, fundamentally solving the problem of misoperation caused by uneven damping. This ensures consistent tactile feedback even under special conditions such as wearing gloves, thereby improving work efficiency.

[0026] Working principle: In the initial state, all keycaps 2 on the keyboard are not pressed, all anti-mistouch mechanisms 3 are in an inactive standby state, the resistance-increasing component 303 does not generate damping, and the keycaps 2 can be pressed normally.

[0027] When an operator puts on gloves and prepares to operate the device, and presses a target keycap 2, the key switch 202 below the keycap 2 is triggered, sending a "key trigger" signal to the control module 4.

[0028] After receiving the signal, the control module 4 immediately identifies the location of the pressed target keycap and simultaneously sends an electrical command to the anti-mistouch mechanism 3 corresponding to the unpressed anti-mistouch keycap.

[0029] Upon receiving the instruction, the resistance-increasing component 303 of the anti-mistouch mechanism 3 is activated, and its internal resistance-increasing element (such as the rubber ball 3037 described later) comes into contact with the keyboard body 1 (such as the rubber washer 102 described later), generating significant frictional resistance, making these anti-mistouch keycaps difficult to be accidentally pressed down.

[0030] When the operator releases the target keycap 2, the keycap resets and stops sending trigger signals. The control module 4 detects this change in state and immediately sends a "reset" command to all anti-mistouch mechanisms 3 that are in the increased resistance state, causing them to de-increase and return to the initial low-damping state, ready for the next operation.

[0031] This embodiment defines the internal driving structure of the resistance-increasing component 303. (Refer to...) Figure 7 The resistance-increasing component 303 includes a first shape memory alloy spring 3032 and a second shape memory alloy spring 3035. Both springs are made of shape memory alloy (SMA) material but have opposite thermally induced phase change characteristics. They are both electrically connected to the control module 4.

[0032] Specifically, the second shape memory alloy spring 3035 is in its natural state at room temperature and without power. When the control module 4 heats it with electricity, it undergoes a phase change and elongates. This elongation is used to drive the resistance-increasing component 303 to produce a resistance-increasing effect.

[0033] Conversely, the first shape memory alloy spring 3032 is in its natural state at room temperature and without energization. When the control module 4 heats it with electricity, it undergoes a phase change and contracts. This contraction is used to release a certain mechanical limit state of the resistance-increasing component 303, thereby helping the mechanism to quickly reset.

[0034] The reverse drive scheme using dual memory alloy springs, one responsible for applying damping and the other for actively unlocking and resetting, effectively solves the problem of slow recovery speed caused by slow natural cooling of unidirectional memory alloys in high-temperature environments. This ensures that the anti-mistouch mechanism can quickly respond to control commands and guarantees the functional stability of the keyboard under high-frequency operation.

[0035] To achieve independent control of the two shape memory alloy springs, refer to Figure 6 The guide member 302 is provided with two electrical contacts 3024, which are connected to the signal output terminal of the control module 4 and electrically connected to the first shape memory alloy spring 3032 and the second shape memory alloy spring 3035, respectively. These two electrical contacts 3024 can be independent physical contacts or part of a multi-pin connector, ensuring that the control module 4 can supply power to the two springs in a time-sharing and independent manner.

[0036] By integrating dedicated electrical contacts on the guide, a clear and reliable independent electrical path is provided for the two memory alloy springs with different functions, simplifying internal wiring, making the structure more compact, and ensuring the accurate transmission of control signals.

[0037] To achieve reliable maintenance of the increased resistance state and rapid unlocking, this embodiment defines a mechanical limiting structure. (Refer to...) Figure 4 , Figure 5 and Figure 7 The drag-increasing component 303 includes a guide shaft 3033 and an inclined block 3034 fixed on the guide shaft 3033. Correspondingly, the hinge 301 has an inclined groove 3013 that matches the shape and angle of the inclined block 3034.

[0038] In the initial standby state, since the first memory alloy spring 3032 is in a naturally extended state, it will push the guide shaft 3033 to a position where the tilt block 3034 is just locked into the tilt groove 3013, forming a stable mechanical limit.

[0039] One end of the first memory alloy spring 3032 is connected to the guide shaft 3033. When a reset is required, the control module 4 energizes the first memory alloy spring 3032 to cause it to contract, thereby pulling the guide shaft 3033 to move, causing the tilting block 3034 to disengage from the tilting groove 3013, and the limit is released.

[0040] The engagement structure between the tilting block and the tilting groove forms a reliable mechanical self-locking mechanism, ensuring the stability and low energy consumption of the increased resistance state and avoiding the need for continuous power supply to maintain the state. Furthermore, the active unlocking by the first shape memory alloy spring enables a fast and reliable reset action, unaffected by ambient temperature.

[0041] To ensure the smooth movement of the guide shaft, refer to Figure 7 The resistance-increasing assembly 303 further includes a mounting plate 3031 and a resistance-increasing guide sleeve 3036. The first shape memory alloy spring 3032, the second shape memory alloy spring 3035, and the guide shaft 3033, among other core components, are all mounted or fixed on this mounting plate 3031, forming a compact module. The guide shaft 3033 passes through the resistance-increasing guide sleeve 3036 and can slide smoothly within it. The guide sleeve 3023 is fixedly connected to the mounting plate 3031.

[0042] By adding a mounting plate and a resistance-increasing guide sleeve, the resistance-increasing assembly is integrated into a standardized module, improving assembly efficiency and precision. Simultaneously, the presence of the resistance-increasing guide sleeve ensures that the guide shaft maintains precise linear motion during force extension and contraction, preventing jamming or wobbling and enhancing the overall reliability of the mechanism.

[0043] To achieve physical separation after the limit is released, refer to Figure 4 and Figure 6 The guide 302 includes a bent plate 3022 and a hinge shaft 3021. The bent plate 3022 is U-shaped and is the main structure of the guide. It is pivotally connected to the internal structure (support not shown) of the keyboard body 1 through the hinge shaft 3021.

[0044] When the first memory alloy spring 3032 contracts, causing the tilt block 3034 to disengage from the tilt groove 3013 and releasing the mechanical limit, the entire guide 302 (along with the resistance-increasing component 303 mounted on it) is no longer constrained by the hinge 301. Under its own weight or the action of an additional return spring, it can rotate around the hinge axis 3021 at a small angle, thereby causing the resistance-increasing component 303 to completely separate from the friction surface (such as the rubber washer 102) of the keyboard body 1.

[0045] When the second memory alloy spring 3035 is energized and in an extended state, the second memory alloy spring 3035 is restored to its original length by de-energizing. As the length of the second memory alloy spring 3035 decreases, the rubber ball 3037 moves inward along the guide sleeve 3023 and away from the rubber washer 102.

[0046] By utilizing a pivoting structure and gravity / elasticity reset, a rapid and low-energy physical separation is achieved after the mechanical lock is released, ensuring that there is no residual contact between the resistance-increasing element and the friction surface, and guaranteeing that the keycap operation can be instantly restored to a smooth, undamped state. The design is ingenious and extremely reliable.

[0047] To improve the fault tolerance and ease of assembly of the mechanism, refer to Figure 5 The hinge 301 is provided with a ball joint 3011 and a hinge groove 3012. The guide 302, through a specific structure thereon, cooperates with the ball joint 3011 and the hinge groove 3012 to form a ball joint connection. This connection method allows the guide 302 to perform omnidirectional fine-tuning within a certain range at the connection point with the hinge 301, in addition to the main pivoting movement.

[0048] By using ball joints, minor errors generated during the manufacturing and assembly of various components can be effectively compensated, reducing the stringent requirements for assembly precision and making the entire linkage mechanism more flexible in motion, thus avoiding stress concentration or movement jamming problems that may be caused by rigid connections.

[0049] This embodiment clarifies the connection method between the anti-mistouch mechanism and the keycap. (Refer to...) Figure 2 and Figure 3 The keycap 2 has a pad 201 and a key switch 202 at its bottom. The key switch 202 is a standard mechanical keyboard switch. The hinge 301 is directly fixedly connected to the pad 201. Meanwhile, the keyboard body 1 has mounting holes 101 at each keycap 2 mounting position, and the key switch 202 of the keycap 2 passes through the corresponding mounting holes 101 and connects to the PCB board below.

[0050] The structure clearly defines the force transmission path between the anti-mistouch mechanism and the keycap. The structure is reasonably designed to ensure that the pressing force and displacement of the keycap can be stably and effectively transmitted to the hinge 301, thereby driving the linkage of the entire anti-mistouch mechanism.

[0051] This embodiment details the implementation method of increasing resistance. Refer to... Figure 1 , Figure 2 and Figure 7 The resistance-increasing element of the resistance-increasing component 303 is a rubber ball 3037. A rubber washer 102 is provided on the keyboard body 1 at a position corresponding to the movement of the rubber ball 3037. Preferably, the rubber washer 102 is directly disposed on the inner wall of the mounting hole 101. When the second memory alloy spring 3035 is energized and extends, it pushes the rubber ball 3037 outward along the guide sleeve 3023 until it makes tight compression contact with the rubber washer 102, generating significant frictional resistance through the high coefficient of friction between the rubber materials.

[0052] The friction pair consisting of a rubber ball and a rubber washer not only provides significant and stable frictional resistance to effectively prevent accidental contact, but also utilizes the elasticity of the material to buffer the impact and noise caused by rigid contact, thereby improving the operating feel and the durability of the mechanism.

[0053] To cope with extreme high temperature and high frequency operating environments, this embodiment proposes a redundant design. Specifically, multiple (e.g., 2 to 4) anti-mistouch mechanisms 3 with identical structures are evenly distributed on the outer side of each keycap 2 (e.g., the peripheral space surrounding the key switch 202).

[0054] If an object is accidentally dropped on the keyboard during use, the resistance-increasing component 303, which has a spring structure inside, can be pressed and contracted by the first memory alloy spring 3032 to move the keycap downward. The elastic resistance (complete locking of non-mechanical structural components) can protect the resistance-increasing component 303 in case of unexpected conditions and prevent accidental damage.

[0055] The firmware algorithm inside the control module 4 is configured to activate one or a portion of the multiple anti-mistouch mechanisms 3 corresponding to the same keycap 2. The operating mode can be: 1) Alternating working mode: Control module 4 records the number of times or the duration of each mechanism's operation, and activates different mechanisms in turn, so that each mechanism has sufficient rest and cooling time.

[0056] 2) Redundancy backup mode: Normally only one primary mechanism is used. When the primary mechanism is detected to be malfunctioning by the sensor described later, it automatically switches to the backup mechanism and issues an alarm.

[0057] By configuring multiple alternating or redundant anti-mistouch mechanisms on a single keycap, the keyboard's durability and reliability are greatly enhanced under high-temperature, high-frequency operating environments. The alternating operation mode provides ample shape recovery time for the unused memory alloy springs, while the redundant backup mode ensures that the keyboard's anti-mistouch function will not be interrupted even if some mechanisms fail.

[0058] The overall working principle of this invention is as follows: In a mechanical keyboard integrating a central control module, each keycap is equipped with an independent anti-mistouch mechanism that can be controlled by electrical signals. In standby mode, all mechanisms are inactive, and keyboard operation is smooth. When a user presses a target key, the control module instantly activates the anti-mistouch mechanisms of all non-target keys. The second memory alloy springs within these mechanisms are electrically excited and extend, driving a mechanical structure to ensure close contact between the rubber ball and other resistance-increasing elements and the friction surface on the keyboard body, thereby generating significant pressing damping and effectively preventing accidental presses. In a more preferred embodiment, the system can also adjust the damping magnitude according to user settings, predict user intentions using proximity sensors and dynamically adjust the anti-mistouch area, utilize redundant mechanisms and self-diagnostic functions to ensure high system reliability, and ensure stable performance under high temperature and high frequency through active heat dissipation. When the user releases the key, the control module instructs the mechanism to reset, and the first memory alloy spring contracts to release the mechanical lock, allowing the mechanism to quickly disengage and restore the keyboard to normal operation. The entire process is fast, precise, and highly intelligent, capable of adapting to various complex industrial operation scenarios.

[0059] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include: In summary, the present invention, through its innovative independent, electromechanical integrated anti-misclick mechanism design, not only solves the problem of misjudgment caused by uneven damping when operating an industrial keyboard while wearing gloves, achieving a uniform and consistent operating feel across the entire keyboard; but also, through the integration of a series of advanced technologies such as dual memory alloy springs, redundancy backup, self-diagnosis, active thermal management, multi-mode control, and predictive sensing, constructs a highly reliable, intelligent, adaptable, and extreme environment-tolerant industrial input solution, comprehensively improving the efficiency, accuracy, and safety of human-machine interaction in industrial production environments.

[0060] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.

[0061] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
