Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, and in particular to a key switch with a pressing feel and a keyboard. Background Technology

[0002] Push-button switches, as a fundamental electronic component widely used in electronic devices, industrial control, and home appliances, directly affect the user experience and product usability through their tactile feedback. Therefore, tactile feedback is one of the key performance indicators in push-button switch design. In existing technologies, some push-button switches use a spring-and-protrusion contact structure to generate tactile feedback. However, through market research and further investigation, the inventors discovered the following problems with these push-button switches: 1. The spring and protrusion gradually wear down under repeated pressing and friction, leading to spring fatigue and a limited lifespan for the push-button switch; 2. Spring noise is generated during the recovery process after being pressed, which significantly impacts the user experience for some users; 3. The tactile feedback of the push-button switch button is monotonous throughout its linear travel. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a push-button switch with a tactile feel.

[0004] This utility model also proposes a keyboard with a key switch having a pressing feel.

[0005] A push-button switch with a pressing feel according to a first aspect embodiment of the present invention includes a base and a button. The button is slidably disposed on the base. The button and the base are respectively provided with a first magnetic block and a second magnetic block. The second magnetic block is located on the side of the first magnetic block. The angle between the center line of the magnetic poles of the first magnetic block and the center line of the magnetic poles of the second magnetic block is β, where 0° < β < 180°. When the button is pressed down, the relative position of the first magnetic block and the second magnetic block changes, thereby generating a pressing feel.

[0006] A push-button switch with a tactile feel according to an embodiment of the present invention has at least the following beneficial effects: Through the above structure, on the one hand, since the first and second magnetic blocks do not generate physical contact or mechanical friction during operation, the lifespan problem caused by spring wear and metal fatigue in traditional switches can be solved, greatly extending the service life of the push-button switch. On the other hand, this application relies on the magnetic force between the magnetic blocks to generate the pressing feel. The entire pressing and resetting process involves no physical action of spring deformation and resetting, nor any collision of mechanical parts, thus eliminating spring noise and meeting the needs of some users in this regard, optimizing their user experience. Furthermore, by setting the center lines of the magnetic poles of the first and second magnetic blocks to have a specific included angle β, the change in the relative position between the two magnetic blocks during the pressing stroke causes a non-linear change in the magnitude and direction of the magnetic force. This unique magnetic circuit design can simulate rich force feedback curves such as tactile feedback and gradual increase in intensity, effectively solving the defect of the single pressing feel of traditional push-button switches in linear travel, and meeting users' needs for personalized, high-quality pressing feel.

Therefore, they should not be construed as limitations on this utility model.

[0020] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Reference Figures 1 to 3This utility model provides a push-button switch with a pressing feel, which includes a base 100 and a button 200. The button 200 is slidably disposed on the base 100. The button 200 and the base 100 are respectively provided with a first magnetic block 310 and a second magnetic block 320. The second magnetic block 320 is located on the side of the first magnetic block 310. The magnetic pole center line L1 of the first magnetic block 310 is arranged in the vertical direction. The angle between the magnetic pole center line L1 of the first magnetic block 310 and the magnetic pole center line L2 of the second magnetic block 320 is β, where β = 90°. When the button 200 is pressed down, the relative position of the first magnetic block 310 and the second magnetic block 320 changes, thereby generating a pressing feel.

[0022] Through the above structure, on the one hand, since the first magnetic block 310 and the second magnetic block 320 do not generate physical contact or mechanical friction during operation, the lifespan problem caused by spring wear and metal fatigue in traditional switches can be solved, greatly extending the service life of the push-button switch. On the other hand, this application relies on the magnetic force between the magnetic blocks to generate the pressing feel. The entire pressing and resetting process does not involve the physical action of spring deformation and resetting, nor does it involve collisions of mechanical parts, thus eliminating spring noise and meeting the needs of some users in this regard, optimizing their user experience. Furthermore, by setting the center lines of the magnetic poles of the first magnetic block 310 and the second magnetic block 320 to have a specific included angle β, the change in the relative position between the two magnetic blocks during the pressing stroke of the button 200 will cause nonlinear changes in the magnitude and direction of the magnetic force. This unique magnetic circuit design can simulate rich force feedback curves such as tactile feedback and gradual increase in intensity, effectively solving the defect of the single pressing feel of traditional push-button switches in linear travel, and meeting users' needs for personalized and high-quality pressing feel.

[0023] In this embodiment, the center line L1 of the magnetic poles of the first magnetic block 310 is set along the vertical direction, and the angle between the center line L1 of the magnetic poles of the first magnetic block 310 and the center line L2 of the magnetic poles of the second magnetic block 320 is β, where β = 90°. In other words, the direction of the magnetic poles of the first magnetic block 310 is parallel to the pressing direction, and the direction of the magnetic poles of the second magnetic block 320 is perpendicular to the pressing direction. The effect of this design is twofold: First, when the button 200 is pressed, the perpendicular and parallel magnetic fields interact during relative motion, and the magnetic force undergoes a drastic change at a critical reversal. This instantaneous reversal of the magnetic force at the critical point provides the user with an extremely clear, crisp, and strong tactile feedback, resulting in a very high degree of operational confirmation. Second, the 90° angle configuration makes the gradient of magnetic force change steepest near the critical point. This means that a clear and powerful tactile feedback can be generated within a very short stroke using a relatively small magnet or a weak magnetic force.

[0024] In some embodiments, the magnetic pole center line L1 of the first magnetic block 310 is arranged in a horizontal direction, and the angle between the magnetic pole center line L1 of the first magnetic block 310 and the magnetic pole center line L2 of the second magnetic block 320 is β, where β = 90°.

[0025] In some embodiments, the magnetic pole center line L1 of the first magnetic block 310 and the magnetic pole center line L2 of the second magnetic block 320 are both inclined, and the included angle between the magnetic pole center line L1 of the first magnetic block 310 and the magnetic pole center line L2 of the second magnetic block 320 is β, where β = 90°.

[0026] In some embodiments, the magnetic pole center line L1 of the first magnetic block 310 and the magnetic pole center line L2 of the second magnetic block 320 are both inclined, and the included angle between the magnetic pole center line L1 of the first magnetic block 310 and the magnetic pole center line L2 of the second magnetic block 320 is β, where β = 60°.

[0027] In this embodiment, the push-button switch is a magnetic shaft switch, with the S and N poles of the first magnetic block 310 positioned vertically. It is understood that the keyboard has a Hall element located below the push-button switch.

[0028] With the above structure, the first magnetic block 310 can serve as a magnetic block that cooperates with the Hall element in a magnetic shaft switch. Specifically, when the button 200 is pressed, the first magnetic block 310 moves accordingly, causing a change in the magnetic field strength at the location of the Hall element. The Hall element can accurately detect this change and convert it into an electrical signal.

[0029] In some embodiments, the number of second magnetic blocks 320 is set to two, three, etc.

[0030] This invention also proposes a keyboard that includes the aforementioned key switches with tactile feedback. This structure extends the service life and eliminates spring noise.

[0031] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
