Description

Technical Field

[0001] This utility model relates to a keyboard with a backlit panel, belonging to the field of computer equipment technology. Background Technology

[0002] A mechanical keyboard is a type of keyboard that uses key switches to record input. These switches provide physical feedback for each key, letting the user know that their keystrokes have been recorded. Mechanical keyboards are often used in fields that require precise and repetitive input, such as data entry, gaming, and programming.

[0003] In the existing technology, keyboards with backlighting have the following drawbacks:

[0004] The lighting display effect is monotonous: it is mostly a button backlight design, with fixed light colors and patterns that cannot be customized, resulting in a poor user interaction experience;

[0005] Unreasonable visual angle: Most light panels are flat designs with an angle of ≤30° with the user's line of sight, which easily produces reflections with a reflectivity of ≥40%, making the light content difficult to see. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this utility model provides a keyboard with a light panel. Through the design of a V-shaped light panel, a light guide module, and an independent control unit, it realizes personalized light display, anti-reflective viewing angle, and modular assembly, thereby improving the user experience.

[0008] A keyboard with a backlight panel includes a keyboard body, a mounting base is provided on the front side of the keyboard body, and a backlight panel assembly is provided inside the mounting base. The backlight panel assembly provides different colors and patterns of light during use to enhance the user experience. The backlight panel assembly includes a panel cover, the cross-section of which is V-shaped, and the upper surface of the panel cover is opposite to the user's line of sight during use.

[0009] Preferably, a palm rest is provided on the rear side of the keyboard body.

[0010] Preferably, the front side of the mounting base is provided with a power interface and a selection switch for switching the connection mode between the keyboard body and the computer host.

[0011] Preferably, the rear side of the mounting base is provided with several limiting members, the limiting members are in the shape of an L, the front side of the keyboard body is provided with several notches corresponding to the limiting members, and the bottom of the mounting base is connected to the base plate by screws.

[0012] Preferably, the bottom of the panel cover is provided with a base plate, the inner wall of the panel cover is provided with a positioning plate, the positioning plate has several through holes, multiple light guide columns are inserted into the positioning plate through the several through holes, the bottom end of the multiple light guide columns is provided with a light guide base plate, and the upper surface of the base plate is provided with an LED light panel.

[0013] Preferably, the lower surface of the base plate is provided with a plurality of connectors, which are connected to the mounting base by screws.

[0014] Preferably, a control unit is provided on one side of the LED light panel.

[0015] Preferably, light-blocking cotton is provided between the outer side of the positioning plate and the inner wall of the panel cover.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The V-shaped structure of the panel cover has an angle of 160-175° that matches the user's line of sight, with a reflectivity of ≤15%, which is significantly lower than that of a flat panel, allowing the light content to be clearly seen even in strong light environments.

[0018] The lighting panel assembly is detachably connected to the mounting base via connectors, reducing replacement costs when a single module is damaged, eliminating the need to replace the entire keyboard. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 This utility model provides a technical solution:

[0030] like Figure 1 and Figure 2 As shown, a keyboard with a backlight panel includes a keyboard body 9, a mounting base 10 on the front side of the keyboard body 9, and a backlight panel assembly inside the mounting base 10. The backlight panel assembly provides different colors and patterns of light during use, enhancing the user experience. The backlight panel assembly includes a panel cover 1, the cross-section of which is V-shaped. During use, the upper surface of the panel cover 1 is opposite to the user's line of sight. The panel cover 1 is made of polycarbonate (PC) material, the cross-section is V-shaped with an included angle of 175±15°, the upper surface is a frosted light-transmitting surface with a light transmittance of 85% and a haze of 60%, and the lower surface is a mirror reflective layer, which effectively reduces reflection, making the reflectivity ≤15%.

[0031] Furthermore, a palm rest 14 is provided on the back of the keyboard body 9. The palm rest 14 is made of memory foam material with a thickness of 20mm and is covered with PU leather. It is connected to the back of the keyboard body 9 by Velcro, conforming to the natural curve of the palm and reducing fatigue during long-term use.

It supports customizing the light color to 16 million colors, dynamic patterns such as breathing, flowing water, and custom animations via keyboard shortcuts or a mobile APP, with a response latency of ≤50ms.

[0037] A light-shielding cotton with a thickness of 2mm is provided between the outer side of the positioning plate 4 and the inner wall of the panel cover 1 to prevent light crosstalk between adjacent light guide columns 5 and ensure clear pattern display.

[0038] The workflow of this embodiment is as follows:

[0039] During installation:

[0040] The limiting member 11 of the mounting base 10 is inserted into the notch of the keyboard body 9. The base plate 2 is fixed to the mounting base 10 with screws through the connector 3. The palm rest 14 is attached to the back of the keyboard body 9 with Velcro. The control unit 8 is connected to the keyboard motherboard ribbon cable.

[0041] When using:

[0042] The connection method can be switched between wired / Bluetooth / 2.4G by selecting switch 13. The battery life is ≥30 hours in wireless mode when powered by power interface 12 or charging. Press the keyboard combination key such as "Fn+F12" to wake up control unit 8. Select the light color and pattern through shortcut keys or APP, such as synchronized skill cooldown animation in games, or display clock in office. The light source of LED light panel 7 is uniformly distributed by light guide plate 6 and then conducted to panel cover 1 through light guide column 5. The V-shaped panel matches the angle of the user's line of sight, clearly displaying the light content without reflection interference.
