[0026] like Figures 1 to 6 The knob shown includes a knob body 1, which includes a display screen 2 for displaying function switching information and a movably rotatable part 3, which can rotate relative to the display screen 2.

[0027] This invention features a display screen for showing function switching information and a rotating part. When a user needs to switch functions or adjust information, they rotate the rotating part. At this time, the display screen shows the function menu and adjustment information. The user can rotate the rotating part according to the function information on the display screen to complete the function switch without having to look at the scale markings on the computer screen or keyboard knobs. This effectively solves the problem that existing keyboards are often equipped with knobs for quick adjustment of functions such as volume, brightness, and voice. However, during the function switching process, users need to frequently look at the scale markings on the computer screen or keyboard knobs, which easily distracts the user and seriously affects operability and convenience.

[0028] Furthermore, when the user rotates the rotating part 3, the display screen 2 will not rotate with the rotating part 3, effectively ensuring that the function information can be displayed continuously and clearly.

[0051] like Figures 1 to 6 A sliding mechanism is provided between the rotating part 3 and the mounting base 4 shown, and the rotating part 3 can rotate relative to the mounting base 4 through the sliding mechanism;

[0052] Furthermore, the sliding mechanism is designed to allow the rotating part 3 to rotate horizontally relative to the mounting base 4; secondly, the sliding mechanism facilitates smoother and more fluid sliding of the rotating part 3, and helps reduce friction between the rotating part 3 and the mounting base 4.

[0053] Specifically, the rotating part 3 is equipped with an encoder. When the rotating part 3 rotates, the encoder can identify the rotation angle of the rotating part 3. At this time, the encoder transmits the rotation information to the circuit board 91.

[0054] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the sliding mechanism includes a slider extending from the inner wall of the rotating part 3 toward the mounting base 4 and a slide rail on the mounting base 4. Because the slider extends toward the mounting base 4, a rotation gap 92 is formed between the rotating part 3 and the mounting base 4. The slider and the slide rail are slidably connected, and the mounting base 4 cannot rotate in the horizontal direction under the action of the limiting member, so that the rotating part 3 can rotate in the horizontal direction relative to the mounting base 4.

[0055] Optionally, the cross-section of the slider is inverted "U" shape, and the cross-section of the slide rail is "U" shape.

[0056] like Figures 1 to 6 The mounting base 4 shown has a connecting protrusion 41 on the side near the shaft 5. The limiting member is located on the side of the shaft 5 near the mounting base 4, and the limiting member has a limiting port that is inserted and engaged with the connecting protrusion 41.

[0057] Furthermore, the limiting member is fixedly installed on the inner wall of the shaft 5. The limiting port and the connecting protrusion 41 have the same shape and size. The limiting port and the connecting protrusion 41 are inserted and matched so that the mounting base 4 cannot rotate in the horizontal direction.

[0058] Optionally, the cross-sections of the connecting protrusion 41 and the limiting port are both rectangular.

[0059] Furthermore, by connecting the protrusion 41 and the limiting port, the precise connection between the shaft 5 and the mounting base 4 can be ensured, which helps to eliminate assembly errors and allows the two to fit together tightly. The precise connection can reduce shaking and displacement after assembly, which helps to improve the stability and accuracy of the equipment.

[0060] like Figures 1 to 6 The cross-section of the display screen 2 shown is circular;

[0061] Furthermore, the circular cross-section of the display screen 2 matches the overall structural shape of the knob body 1, which helps to enhance the overall harmony of the knob body 1.

[0062] Furthermore, compared to complex polygonal or multi-angle setups, the manufacture of circles is relatively simple, which helps to reduce the complexity and cost of production.

[0063] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the display screen 2 has a radius of 1.7cm. The display screen 2 with a radius of 1.7cm has a relatively compact structure, which is conducive to installation on the keyboard and will not take up too much space on the keyboard. In addition, it helps to reduce the overall weight of the device and improves portability.

[0064] like Figures 1 to 6 The display screen 2 shown is a TFT display screen;

[0065] Furthermore, TFT displays can provide high-resolution display effects, making images clearer and more detailed. When displaying text and images, TFT displays can present delicate and realistic picture effects, meeting users' high requirements for picture quality.

[0066] Furthermore, TFT displays have a fast response time, making them suitable for displaying rapidly changing images. They can quickly respond to user input and update the displayed content in real time. When displaying content, TFT displays can present a smooth and ghosting-free picture effect, which helps to improve the user's viewing experience.

[0067] like Figures 1 to 6 The outer wall of the rotating part 3 shown is provided with an anti-slip component to enhance friction.

[0068] Furthermore, the anti-slip component increases the friction between the rotating part 3 and the user's fingers, making the rotation of the rotating part 3 smoother and reducing slippage. In addition, the anti-slip component allows the user to more precisely control the rotation angle of the rotating part 3.

[0069] Optionally, in some embodiments, the anti-slip element is an anti-slip protrusion provided on the outer wall of the rotating part 3.

[0070] Optionally, in some embodiments, the anti-slip element is an anti-slip stripe provided on the outer wall of the rotating part 3.

[0071] like Figures 1 to 6 The keyboard shown includes a keyboard body 6, which includes a knob body 1 as described above, and the keyboard body 6 is provided with a mounting area for mounting the knob body 1.

[0072] Furthermore, the keyboard body 6 is provided with a circuit board 91, and the knob body 1 is provided with a connector 93 that connects to the circuit board 91. The connector 93 is located at the bottom of the switch 5.

[0073] Specifically, the function switching menu displayed on screen 2 includes: boot animation, driver animation, date and time, lighting effects / colors, lighting brightness / rate, volume adjustment, and language selection.

[0074] Furthermore, by setting an installation area on the keyboard body 6 for mounting the knob body 1, users can quickly find the installation location of the knob body 1, which helps to reduce the user's installation time.

[0075] like Figures 1 to 6 The installation area shown includes a mounting port 61 located on one side of the keyboard body 6 for mounting the knob body 1;

[0076] Furthermore, the mounting port 61 is located on one side of the keyboard body 6, which helps to free up space in the central area of ​​the keyboard body 6, thereby providing more space for key arrangement; secondly, the setting of the mounting port 61 on one side of the keyboard body 6 helps users to clearly distinguish the position areas of the knob body 1 and other keys, which helps to reduce the occurrence of user misoperation and effectively improves the intuitiveness and efficiency of user operation.

[0077] like Figures 1 to 6 The keyboard body 6 shown is equipped with auxiliary buttons. The knob body 1 and the auxiliary buttons work together to allow the display screen 2 to adjust the displayed information.

[0078] Specifically, the auxiliary key is the FN key located on the main body of the keyboard 6.

[0079] Furthermore, when the knob body 1 is connected to the keyboard body 6, the keyboard body 6 and the knob body 1 are connected. At this time, the default function of the knob body 1 is to adjust the volume. Pressing the knob body 1 mutes the volume. When the user needs to select a function to switch, he / she first presses the FN key and then presses the knob body 1. At this time, the display screen 2 can display the function switching menu. When the user rotates the knob body 1, he / she can select the function according to the function switching menu displayed on the display screen 2. Finally, he / she presses the knob body 1 to complete the function selection confirmation.

[0080] Working principle:

[0081] The display screen 2 is mounted on the mounting base 4. A limiting member is provided between the mounting base 4 and the shaft 5 to prevent the mounting base 4 from rotating in the horizontal direction. A sliding mechanism is provided between the rotating part 3 and the mounting base 4. The sliding mechanism includes a slider extending from the inner wall of the rotating part 3 toward the mounting base 4 and a slide rail on the mounting base 4. Because the slider extends toward the mounting base 4, a rotation gap 92 is formed between the rotating part 3 and the mounting base 4. The slider and the slide rail are slidably connected, and the mounting base 4 cannot rotate in the horizontal direction under the action of the limiting member, so that the rotating part 3 can rotate in the horizontal direction relative to the mounting base 4. A dome switch is provided between the display screen 2 and the mounting base 4. The dome switch can provide a press contact on the display screen 2. The user can press the press contact on the display screen 2 in the vertical direction. The dome switch transmits the press signal to the circuit board 91. Finally, the dome switch is reset. In addition, an encoder is provided on the rotating part 3. When the rotating part 3 rotates, the encoder can identify the rotation angle of the rotating part 3. At this time, the encoder transmits the rotation information to the circuit board 91.

[0082] The implementation method of this embodiment is as follows:

[0083] A knob with a screen includes a knob body 1, which includes a display screen 2 for displaying function switching information and a movably mounted rotating part 3. The knob body 1 has a mounting base 4 for mounting the display screen 2 and a shaft 5 fixedly connected to the mounting base 4. A limiting member is provided between the mounting base 4 and the shaft 5 to prevent the mounting base 4 from rotating horizontally. A sliding mechanism is provided between the rotating part 3 and the mounting base 4. The sliding mechanism includes a slider extending from the inner wall of the rotating part 3 towards the mounting base 4 and a slide rail on the mounting base 4. Because the slider extends towards the mounting base 4, a rotational gap 92 is formed between the rotating part 3 and the mounting base 4. The slider and the slide rail are slidably connected, and the mounting base 4 cannot rotate horizontally under the action of the limiting member, allowing the rotating part 3 to rotate horizontally relative to the mounting base 4. A dome switch is provided between the display screen 2 and the mounting base 4, and the dome switch can provide a press contact on the display screen 2. Users can press the touch points on the display screen 2 vertically. The dome switch transmits the pressing signal to the circuit board 91, and finally the dome switch resets. In addition, the rotating part 3 is equipped with an encoder. When the rotating part 3 rotates, the encoder can identify the rotation angle of the rotating part 3. At this time, the encoder transmits the rotation information to the circuit board 91. When the user needs to switch functions or adjust information, he / she rotates the rotating part 3. At this time, the display screen 2 can display the function menu and adjustment information. The user can rotate the rotating part 3 according to the function information on the display screen 2 to complete the function switch. There is no need to look at the scale marks on the computer screen or keyboard knob. This effectively solves the problem that existing keyboards are often equipped with knobs for quick adjustment of functions such as volume, brightness and voice. However, during the function switch process, users need to frequently look at the scale marks on the computer screen or keyboard knob, which can easily distract the user and seriously affect operability and convenience.

[0084] A keyboard includes a keyboard body 6, which includes a knob body 1 as described above. The keyboard body 6 has an installation area for mounting the knob body 1. When the knob body 1 is connected to the keyboard body 6, the keyboard body 6 and the knob body 1 are connected. At this time, the default function of the knob body 1 is to adjust the volume. Pressing the knob body 1 mutes the volume. When the user needs to select a function, he / she first presses the FN key and then presses the knob body 1. At this time, the display screen 2 can display a function switching menu. When the user rotates the knob body 1, according to the function switching menu displayed on the display screen 2, he / she finally presses the knob body 1 to complete the function selection confirmation.
