Description

Technical Field

[0001] The present application relates to the field of switch buttons, in particular to a double-stroke switch button. Background Art

[0002] In existing keyboard technology, the stroke length of the switch key is usually fixed, which makes most standard keyboards less adaptable in different scenarios. Most current keyboard designs are designed to balance typing experience and response speed, but keys with a single stroke design cannot provide the best use effect in some specific usage scenarios. For example, in some noise-sensitive environments (such as nighttime use or quiet office spaces), a long key stroke may cause obvious knocking sounds, which not only affects the user's operating experience, but may also disturb people around. In addition, a longer stroke usually requires a greater pressing force, and such a design will increase the user's operating burden during long-term use, especially for those who need to input frequently, long-stroke keys are prone to finger fatigue. On the contrary, in scenarios that require fast response and high-speed typing, a shorter key stroke may result in insufficient key feedback, which in turn affects the accuracy and response speed of the operation, resulting in false touches or inaccurate operations. It can be seen that keys with fixed strokes cannot meet the changing usage requirements and limit the user's operating experience in different environments.

[0003] Although existing technologies are suitable for some common usage scenarios, fixed key strokes often cannot meet personalized needs in different usage environments. For example, in an environment that requires quiet operation, a longer key stroke not only produces a loud knocking sound, but also requires a greater force when pressing, which increases fatigue during long-term use. In some situations that require efficient input or quick response, such as programming, typing tests, or game operations, a longer stroke may reduce the response speed, making it difficult for users to achieve fast input or precise operation. Although the key stroke of the prior art can meet some standardized needs, the limitations of the fixed stroke design gradually emerge when faced with different usage scenarios and personalized needs. Therefore, in the face of diverse usage needs, the traditional single-stroke key technology is particularly insufficient in terms of adaptability and flexibility.

[0004] At the same time, longer key travel still has advantages that cannot be ignored in certain specific scenarios. For scenarios that require precise input and long-term typing, a longer travel can provide clearer press feedback, thereby helping users avoid false touches and inaccurate operations and improving input stability. Long-stroke keys usually provide more obvious tactile feedback, allowing users to clearly perceive the action of each key, increasing the accuracy and comfort of typing, and are particularly suitable for tasks that require high input accuracy, such as programming and document editing. In addition, long-stroke keys can effectively reduce the occurrence of misoperations, because it usually takes a lot of force and a certain distance to fully press the key, which greatly reduces the probability of false touches. For some high-end mechanical keyboard users, long-stroke keys are believed to provide a richer touch and a better user experience, greatly improving the overall operational satisfaction.

[0005] However, the limitation of single-stroke keys makes it difficult to take into account these different needs in keyboard design, especially in diversified application scenarios, where users often want to be able to switch key strokes according to specific environments and tasks in order to optimize the operating experience and improve efficiency. Therefore, it is particularly important to develop a switch key technology that can provide adjustable stroke. Summary of the invention

[0006] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a dual-stroke switch button that can flexibly adjust the stroke length of the key to adapt to different usage requirements. In a quiet environment, users can choose a shorter key stroke, which can not only reduce the noise of the key, but also reduce the force of pressing, and reduce fatigue when typing for a long time; at the same time, a shorter stroke can increase the response speed of the key, making typing faster and the operation more sensitive. In scenarios that require higher-precision input, a longer key stroke can provide clearer tactile feedback, increase the stability and accuracy of the key, thereby avoiding false touches and improving input accuracy, which is particularly suitable for tasks that require long-term work or delicate operations.

[0007] To achieve the above-mentioned purpose, the present application discloses a double-stroke switch button, which includes a housing, a shaft body vertically inserted into the housing from the top downward, a stroke adjustment part inserted from the bottom and connected with the housing, and a trigger mechanism installed on the stroke adjustment part of the housing, wherein a reset spring for resetting the shaft body after it moves downward is installed in the housing; a guide mechanism for linearly guiding the shaft body is arranged in the housing; the shaft body includes a handle, a rod extending downward from the top of the handle, and a working part installed on the side of the handle for working with the trigger mechanism, and the bottom end of the rod is relatively matched with the stroke adjustment part; for installing the stroke adjustment part, a mounting groove is arranged at the bottom of the housing, and a high-stroke clamping position and a low-stroke clamping position are opened on the groove wall of the mounting groove; the stroke adjustment part is inserted into the housing from the mounting groove and cooperates with the trigger spring, and the trigger mechanism moves synchronously with the stroke adjustment part. To achieve the adjustment and installation of the stroke adjustment part, the stroke adjustment part is provided with a hanging ear, and the stroke adjustment is achieved by cooperating the hanging ear with the high-stroke clamping position or the low-stroke clamping position. Synchronously, since the trigger mechanism is driven to move upward or downward synchronously during adjustment, the triggering of the working part and the spring switch is also adjusted synchronously.

[0008] Furthermore, a magnetic block is embedded in the working part, and correspondingly, the trigger mechanism is a Hall element, and the trigger is achieved by sensing the magnetic field size of the magnetic block through the Hall element.

[0009] Furthermore, the working part is a spring switch, which has a fixed piece and a movable piece, wherein the movable piece cooperates with the working part and is pushed by the working part to contact and conduct with the fixed piece.

[0010] Furthermore, a guide groove for positioning and guiding the trigger mechanism is provided in the working part housing, and accordingly, the working part and the stroke adjustment part are axially constrained and radially free, so that when the stroke adjustment part is operated and rotated, the relative cooperation between the trigger mechanism and the working part is not affected.

[0011] Furthermore, the bottom end of the rod is spherical, so that the sound when the shaft rod collides with the stroke adjustment part is clearer.

[0012] Compared with the prior art, the present invention has at least one of the following beneficial effects: 1. Adapt to diverse usage needs: Through the dual-stroke design, users can flexibly adjust the stroke length of the keys according to different usage scenarios. In a quiet environment, choose a shorter stroke to reduce noise and pressure; in situations where precise input is required, choose a longer stroke to enhance the tactile feedback and stability of the keys and improve the accuracy of the operation. This adjustability allows the keys to optimize the user experience according to specific needs.

[0013] 2. Improve operational comfort and efficiency: The short-stroke design can improve the response speed of the keys, allowing users to quickly complete input and reduce key fatigue in scenarios that require quick response, such as typing and gaming. The longer-stroke design provides clearer tactile feedback and avoids false touches, which is particularly suitable for long-term work or delicate operations, and improves overall input stability and comfort.

[0014] 3. Enhanced durability and stability: Through the design of the stroke adjustment part, the stroke length of the key can be easily adjusted according to needs. At the same time, the synchronous adjustment of the trigger mechanism and the working part ensures the stability and reliability of the key. In addition, the use of magnetic blocks and Hall components reduces the wear of traditional mechanical triggers and improves the service life and long-term stability of the keys.

[0015] 4. Reduce noise and vibration: The bottom end of the rod designed with this technology is spherical, which can make the sound when the shaft and the stroke adjustment part collide clearer.

[0016] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description parts of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See attached Figure 1-3 This embodiment provides a dual-stroke adjustable switch button, which can adjust the stroke length of the button according to different usage requirements, so as to adapt to different usage scenarios and optimize the user's operating experience. The design of the switch button provides the best response speed and tactile feedback in multiple scenarios through the adjustable stroke mechanism. The entire button includes a shell 1, a shaft 2, a stroke adjustment part 5, a trigger mechanism 3, a reset spring 4, a guide mechanism and other key components. The adjustability, stability and reliability of the button are achieved through precise matching between the various parts.

[0025] First, the shell 1, as the external protection structure of the key, is usually made of durable plastic or metal materials (such as ABS plastic, polycarbonate or aluminum alloy) to ensure the strength and long service life of the key. The shape and size of the shell 1 can vary according to specific needs. It is generally rectangular or cylindrical and suitable for installation in a keyboard or other control device. A mounting groove 101 is provided inside the shell 1 for installing and fixing the stroke adjustment part 5. A high stroke position and a low stroke position are provided in the groove wall for the hanging ears of the stroke adjustment part 5 to cooperate with to achieve different stroke adjustments. In addition, the shell 1 also includes a reset spring groove and a guide groove. The reset spring 4 groove is used to accommodate the reset spring 4, and the guide groove ensures that the shaft body 2 can only move in the vertical direction when the key is pressed, thereby avoiding lateral displacement and ensuring the stability of the key.

[0026] The shaft body 2 is the core component of the switch button, which is mainly responsible for executing the downward movement of the button and cooperating with the stroke adjustment part 5 to achieve the stroke adjustment of the button. The shaft body 2 is made of a material with good wear resistance (such as POM plastic, aluminum alloy or stainless steel) to ensure its stability and durability during long-term use. The shaft body 2 consists of three parts: a handle 201, a rod 202 and a working part 203. The handle 201 is located at the upper end, which is usually the contact part of the user's finger; the rod 202 extends downward from the top of the handle 201 and cooperates with the bottom end of the stroke adjustment part 5 to control the downward stroke of the button; the working part 203 is installed on the side of the shaft body 2, and the switch is triggered by cooperating with the trigger mechanism 3. The downward movement of the shaft body 2 maintains the linear movement of the shaft body 2 by cooperating with the guide groove inside the shell 1, avoiding the problem of non-axial offset.

[0027] The stroke adjustment part 5 is a key component of the switch button design. It can change the stroke length of the button by adjusting the matching position of the hook and the latch. The stroke adjustment part 5 is usually made of metal or high-strength plastic material, and has strong pressure resistance and wear resistance. This component cooperates with the high-stroke latch or the low-stroke latch through the hook, and the user can choose different key strokes according to needs. In the long-stroke mode, the hook cooperates with the high-stroke latch, and the downward distance of the shaft body 2 is longer, providing clearer tactile feedback; while in the short-stroke mode, the hook cooperates with the low-stroke latch, and the downward distance of the shaft body 2 is shortened, thereby improving the response speed of the button, which is suitable for high-speed typing or fast response scenarios. The stroke adjustment part 5 maintains synchronous movement with the trigger mechanism 3 through its built-in synchronization mechanism to ensure that the trigger condition of the trigger mechanism is always consistent with the selected stroke.

[0028] The trigger mechanism 3 is a core component in the switch button for completing the switch operation. The trigger mechanism 3 in this embodiment has two triggering modes: a spring switch and a Hall element in conjunction with a magnetic block. The spring switch includes a fixed plate and a movable plate. The movable plate cooperates with the working part 203. When pressed, the movable plate is pushed by the working part 203 to make the fixed plate contact and conduct, completing the switch operation of the circuit. The design of the spring switch has very intuitive tactile feedback, which can help users confirm whether the button is successfully triggered, and has good durability.

[0029] Another triggering method is the combination of Hall elements and magnetic blocks. In this design, a magnetic block is embedded in the working part 203, and the trigger mechanism 3 uses a Hall element. The Hall element can sense the strength and direction of the magnetic field. When the magnetic block is close to the Hall element, the Hall element will sense the change in the magnetic field, thereby triggering the output of the switch signal. Compared with traditional mechanical contact switches, the combination of Hall elements and magnetic blocks has higher reliability and durability, avoiding wear and aging of the contact points. This triggering method has a long service life and is suitable for application scenarios that require high durability and high reliability, such as gaming keyboards or professional input devices.

[0030] In order to ensure the stability of the trigger mechanism 3 during the key pressing process, the cooperation between the working part 203 and the stroke adjustment part 5 adopts a precise guide design. The working part 203 cooperates with the guide mechanism in the housing 1 through the guide groove to ensure that it maintains a stable positioning during the pressing process to avoid position deviation. The design of the guide groove makes the movement of the working part 203 more stable and will not be affected by the lateral force, thereby avoiding the failure of the trigger mechanism 3 or inaccurate response.

[0031] In addition, the spherical design of the bottom end of the shaft 202 helps reduce friction and noise during the keystroke process. The spherical bottom end design can reduce the impact noise between the shaft 2 and the stroke adjustment part 5 during stroke adjustment, while improving the touch of the key, making the key sound crisper when used, and increasing the user's operational feedback. This design helps improve the overall experience of the keystroke, allowing the user to more accurately perceive the state of the keystroke.

[0032] The design of this switch button can provide different advantages in multiple scenarios. When a quiet environment is required, users can choose the short-stroke mode to reduce the noise of the button and reduce the force when pressing, which is suitable for night use or office environments that require quiet operation; in scenarios that require precise input or high-speed response, the long-stroke mode can provide clearer tactile feedback, avoid false touches and improve input accuracy, which is especially suitable for scenarios with fine input such as programming and game operations. Through stroke adjustment, users can flexibly choose the key stroke suitable for the current scenario, thereby improving usage comfort and operating efficiency.

[0033] In summary, this embodiment uses a dual-stroke adjustable design to enable the switch button to adapt to different usage requirements, and can provide the best operating experience whether in a quiet operating environment or in situations where high-speed response and precise input are required. The triggering method of the Hall element and the magnetic block, and the triggering method of the spring switch, provide users with two different triggering mechanisms to meet the durability and feedback requirements of different users. This invention has strong adaptability and market prospects, can effectively solve the shortcomings of the fixed key stroke in the prior art, and provide a more flexible, comfortable and efficient operating experience.
